@bennyb: Ok, so the name of your TV is indeed ’gallery’? The template id you want it to apply to is 12? And the id of the gallery module is indeed 2? If the field for the TV is disappearing then it might mean that it’s working but the gallery module ID is wrong. Check and make sure it’s correct.
@knightknight: The reason why images are stored by page ID is that if a page name changes in MODx, what happens to the directory name in EvoGallery? The module runs independently from MODx itself so, unless you create a plugin that manages the directory names whenever a page is saved, you’ll run into a lot of problems. Better to keep it simple and organized by page ID.
@bennyb: You can set the max width of the thumbnails in the module config. However, if you want more control, set the absolute max width you need for the thumbs and then use something like PHPThumb or another script to control the images on the front-end of your site. I’ve used PHPThumb in many instances with EvoGallery in the past. Works great!
