Hi,
I looking for a plugin. It would have to allow to add some listbox in editOnePic panel where the user must select. For example I put a listbox with some camera reflex and the user have to select obligatory only one. Every time the administrator can to see how many users use this camera or other.
thanks
Use the Custom fields for image description (http://coppermine-gallery.net/demo/cpg14x/docs/index.htm#admin_custom_image) then. It's up to you to modify the code to make it a dropdown field and make the selection mandatory when a user submits the form.
Not a plugin though in Coppermine terms - you're looking for a custom mod. Moving thread accordingly.
As this mod is not trivial I strongly doubt that someone will code this for you. You need it -> you code it, or hire someone to code it for you.
