I have convinced the project team I am currently work with that it is a good move to bring some of their old PDF files in to an HTML5 output and post them as a small online help system. They were generally happy with the idea, since they could still print the topics, but they want to the topics printed from the help to use full-size (or at least bigger) images than the thumbnails used in the help. I found some topics in the forum from 2011 and 2013 discussing the problem, but it seems at that time that Flare didn't have a way to do it elegantly.
Six to eight years later, does anyone know if there's a way to do it in Flare now?

I'm still digging around, but haven't found a feature that does this (or a good workaround), and am hoping that the collective genius of the forums might have something . . .
Thanks,
Tracey
