Hi, I'm using the class-WEBdocs plugin to display a couple of PDFs in my image gallery. Is it possible to make the iFrame larger? Specifically, I want it to be longer to fit the entire PDF using Google Docs. I read that the iFrame size is determined by the image size, but I've tested changing the default size in the template functions and css, but no luck changing the iFrame length. Can you help?

Thank you!

That is set by the image size but on PDFs Zenphoto is most likely not able to read the size at all (as with other formats).

You should never modify files within zp-core. You should instead modify the css of the theme used using the "important" keyword. That should allow you to override the size.
