I'm working on a site that provides Photoshop resources. I would like to create a page offering brushes for download that displays a thumbnail image and a link to a .zip file for each brush set. I was thinking that I could attach the .zip files for all the brush sets to the page and then display the thumbnails. I was wondering if there might be a way to link a thumbnail image to the attachment and then display all of the thumbnails. My initial thought was to add a custom field for attachments that allowed you to upload a thumbnail. Then, use something like this, but modified to output the thumbnail with a link to the attachment itself [ List Post Attachments - Remove Image Thumbnails ] to display all of the previews. Is there an existing plugin that allows you to upload thumbnails as a custom field to attachments, or can you tell me how to do so myself? (Or, if there's a better way to do this, I am all ears!) Thank you!
Personally, I would create a custom post type called brush, and use the featured image facility to provide a representative thumbnail. You could then create an archive-brush.php template to show them all.
