I've tried adding some custom CSS styles using the wysiwyg_custom.css and .php approach however I can't seem to get it working. Ideally I'm trying to add a CSS style so that when an image is uplaoded in a WYSIWYG field, they can apply a class as they won't be able to manually add it using the source code button.
Any suggestions greatly received.
I saw your post didn't get a response. Let me know if you're still working on this and I'll give you a hand.
