Well, the question is quite straighforward and obvious. I have a collection composed of PDF files, and many of them are anciente scanned books, most of them the first page is the book cover, and since they are quite old, most of the covers ar just a green / red cover with no information.
After a few pages, is the page with the catalographic info of the book, which would be perfect to be on the thumbnail for the archive.
Question is, is there a way to customize which page will be the preview, instead of being always the first page? Maybe with a custom field with a number which will be the thumbnail page?
even if I have to hardcode it on omeka itself, any tips on where the page thumb is collected will be appreciated.
it looks pretty obvious to me, hope this possibility comes with newer omeka versions.
