    Hi Zachary,

    thanx for this plugin (I had tried others, but the conflicted with one aspect of my current theme…yours work 🙂 )

    I do have 2 questions: could it be possible to make the images (when they appear in the “Lightbox fashion”, to be centered instead of being sort of, docked on top of the browser?

    And second, I was wondering if there’s anyways we could “control” the way thumbnails show, let me explain what I mean: if I understand well, the thumb is created out of the original “big” image that will show when we click on the thumb. We give the “thumb appearance” a certain size…but I have some images that, when I look at the thumb, let say it shows a portion of the original pic (which seems to be the center). Anyways we can create our own thumb, that could “call” the original image after clicking (2 separated images)? (I hope you get what I mean…it’s just that, let say you have a person on the image (from head to toes), and the thumb shows it’s body say, from pelvis to neck, but would wish the thumb would be his face, know what I mean?)

    Thanx in advance, and congrats, nice plugin!

      Hi Stephane,

      You may try and use CSS to change how the LightBox behaves, I cannot give you specific instructions though and I am not a 100% sure its possible. As for you second question, you may generate your own thumbnails and replace the corresponding thumbnail on the server, CataBlog’s thumbnail files are found in wp-content/uploads/catablog/thumbnails/ directory.

      Good luck

  2. Stephane says:

    Thanx a lot Zachary!

    Awesome! (I should have checked the folders to look for thumbnails before I ask, hehe)

    • Stephane says:

      …is it suppose to be as simple as: with FTP, replace the image in the Thumnails folder and voilà? (because, when I upload and replace the thumb, refresh the page on my website, I still get to see the thumb as it was before I replaced it?



      • Zach says:

        Yeah, it should be that simple as long as the file name is exactly the same. Make sure to clear your browsers cache after your modifications. Holding shift while clicking refresh to force reloading everything on the page.

    It would be greate when I could choose between the browser or flash upload. Flash upload makes many troubles.

    Thanks for this wonderful plugin. i am working on adding pages no support.
    i have been successful so far, but i can’t figure out how are you setting the default values for thumbnail size. Can you please shed some light on this and if you want i will be more than happy to pass on the new code.

    Best Regards

    Hi Zachary Segal,

    very nice plugin!

    I have on question? I need the thumbnail image is a different image then the main image (in the lightbox). Also the width and high of the thumbnail is different then the main image.

    Is this possible?

    Thanks in advance.

    Grt Meez

    • Zach says:

      Let me think about it, but I am not sure this is currently possible with CataBlog.

      • Mees Frenkel Frank says:

        Thanks for your reply. It should be very nice if this is possible.

        I need to show the ‘cover’ of some magazines (thumbnails). When you click on the thumbnail you see a bigger ‘spread’ in the lightbox.

        Thanks in advance.

      • Hi Zachary,


        I find a way to do it with the %SUB-IMAGES%. But how do i manage. If i click on the thumbnail the lightbox open, then i can click ‘next’ to only the subimages. If you reach the last subimage you can’t click any further.

        Is this possible?

        Thanks in advance.

        Grt Meez

        • Zach says:

          I am sorry but this is currently not possible, I will look into adding functionality like this in a future version.

          Thanks again for your interest in CataBlog.

    Hi Zach, very good plugin!! First sorry my bad english, I hope you understand anyway…
    1 question if you can help me:
    when I put a gallery in a post it shows 1 thumbnail for row, I have tried in so many ways to change that, from the Catablog Options in Admin (I don’t see it), from the css (I’m not an expert) trying to change some {display: block} to {display: inline} but it’s still 1 thumbnail for row…
    Have you the magic touch for this? 🙂
    Any help will be appreciated
    Best regards, Claudio

    • Zach says:

      Have you tried loading the gallery template in the CataBlog Options Admin Panel. Just go to the template tab and then select gallery from the drop down menu, click load next to the drop down menu and then click save at the very bottom of the page. You should get a gallery style layout similar to my example page.

    Hi Zach,
    I just discovered CataBlog and I am tinkering with it to see if it will work as a catalog solution for a client. So far I really like the simplicity and features, nice work.

    Since the client has a LOT of products and categories I was hoping to save space by just displaying the thumb and product title on the category page (and alt image if applicable) in multiple columns, and then having the full details/description only on the large lightbox image for each item. Is this possible?


  8. Jim says:

    …or I could read the post above mine and just activate the gallery template.

    Thanks for being one step ahead!

  9. Zach, thank you for the great plug in. Amazingly easy to use and customize! Now that I’ve posted a couple hundred photos using it, and attaching neat little collections in individual blog posts, I couldn’t be happier. But I have a question:

    A bunch of folks have emailed me asking to have the ability to scroll through the galleries. Right now it seems like the only choice is to click to open, then close, then click the next. Any way to put a “next” and “previous” link in each pic?

    All the best, thanks, and great work!

    Hi Zachary,

    I am using your plug in and its great, I only have one question, in order to use a certain font style where would I add this option or change this option, I would like to use Arial font for all the information under my item.


  11. Hi,
    I am using WP 3.2.1 with Buddypress 1.5.1

    This plugin is exactly what I’ve been looking for, however, I have come across a problem.

    When I try to add a new category, when I click the add button, it changes to the loading icon, but nothing happens, it just keeps displaying the icon. Any thoughts on what might be causing this?

    Many thanks

    • Zach says:

      I am curious if you are experiencing a conflict. What happens when you disable BuddyPress and other plugins and use the twenty-ten theme from WordPress?

      Other thoughts would be that your browser has AJAX or JavaScript disabled, which CataBlog requires.

  12. Daniel Liquete says:

    Hi Zach,
    I’m using the CataBlog plugin in a Facebook fanpage iframe. Using the default template, the description and PayPal button overlap the thumbnail on the left by about 10 pixels. I couldn’t locate in the CSS where I could edit this.

    Please direct me where to edit the css to shift the description text 30 pixels or so.


  13. diego2k says:

    Hi Zach i made an add on for your catablog plugin that enable user to make a purchase order and send it by email to some email.

    So if you want to check it out let me know or maybe some users ask you for this feature maybe in a future version of catablog you can introduce 2 hooks that i need in order to doesn’t need to make changes to catablog class to support an addon.

    Thanks for your plugin

  14. Hi Zach,
    Your plugin does appear on my wordpress admin, but still appear on my website?
    I can’t update any logo on my website
    What’s the problem, please?

  15. Anna says:

    Hi Zach, I’m working with catablog and it seems to be perfect other than rather than add to a cart, I’d love to add to a wish list or have the products add to a zero value cart so that my clients can choose a set of images that they like and then either generate a list of products they like or order a free printed sample sheet.

    Do you have any ideas on how to achieve this? I’ve been looking for plugins with short codes that might work but no success, I’ve also explored making all the images 0.01 and then trying to offer a refund code but no success with paypal. I’d very much appreciate your ideas on this as I have several art licensing and photography clients that would be interested.

    thanks Anna

    • Zach says:

      CataBlog has a highly configurable template rendering system that lets you control exactly how your catalog items are displayed. You may use the %BUY-NOW-BUTTON% token in the CataBlog Template and then set a Store Template in the CataBlog Options Admin Panel to make whatever button you need for any shopping cart solution you wish to use. It should be pretty simple if you look at the example PayPal Store Template.

  16. Greg says:

    Thanks for this! Catablog is the preferred plugin for my site. Would absolutely LOVE the ability to easily add custom fields.

  17. Craig says:

    Hi Zach,

    I have tried using your plugin but whenever I upload a JPEG image, all that appears is a blank thumbnail or a red cross. Any suggestions on how to over come this?



    • Zach says:

      Are there any error messages?
      Does your server have PHP 5 with the GD extension installed?
      Are your JPEG images corrupted? Try another image exported directly from a program like Photoshop.

      Hope you figure it out.

  18. Michelle says:

    Hi Zach – I am with Greg – would LOVE to be able to add custom fields. Any chance you would be willing / able to add some fields for me for a fee?


  19. Momo says:

    Hi Zach,

    I have installed Catablog to my site, but I cannot link the items to the desired section.. As far as I understood, I should paste the URL into the “link” field, right? For example I put http://www.kafedelfina-shu.com/new/?page_id=33 or just /?page_id=33 , and nothing happens.

    Please help!

    Thank you!

    • Zach says:

      When you use the default CataBlog template the link setting should only create a link for the title of the catalog item, not the thumbnail. If you want the thumbnail to link to the “link setting” then you need to customize your template. You will want to replace the %MAIN-IMAGE% token with your own HTML code, look at the gallery template for an example of building your thumbnail image HTML without the %MAIN-IMAGE% token. Good luck.
