Well I released another beta version of CataBlog today in the quest to add multiple images per catalog item support. This version has a more refined interface, along with what I believe to be complete integration within the plugin. Support for importing and exporting sub images in CSV and XML formats has been added, along with better file handling and form validation for all image uploads. This version also includes quite a few tweaks and enhancements to the interface. All in all I feel like it is a decent pre-release and if I get a generally positive response, it will most likely be the next stable release.
So now, how does one add multiple images per catalog item? First you must create a catalog item by uploading a primary or main image along with a title. Once the catalog item has been created you will notice two links underneath the main image, Replace Main Image and [+] Add Sub Image. These links will open a form in a new floating window that allows you to either replace your main image, or add a new image to your catalog item. Once you have added a few sub images, you may change their order with drag and drop in the edit catalog item form. Make sure to click Save Changes after you change the sub images order. Deleting a sub image is even easier, move your mouse over the image you wish to delete and click the red x.
Looking forward to hearing ideas, complaints, compliments and all other feedback about this release. You may download it directly or go to the wordpress.org page to learn more. Because this is a beta release you can not download or install this version using the WordPress Admin Plugins panel.
