Actually, I have a content type with 2 fields, image field (multiple) which will contain some pictures and an attachment field (accept only one file) which is file of type PDF.
I have a view where I put my gallery and each picture opens in a colorbox. The PDF file (actually global pdf for all images) is only a button.
There was a change and the new requierement is: "For every image that goes up, must have its own PDF. Every image should have its own associated file."
Another requirement is, if the image is opened on a colorbox also appears a button (in the colorbox) which displays the PDF associated with the corresponding image.
Any idea??? Sorry for my bad english.
