Editing image title and description via CKEDITOR fully works, with the right controls (bold/italic/underline/bullet list/numbered list/link add/link remove).

I couldn't get source HTML code editing working with CKEDITOR because I can't get ckeditor working from localhost OR tacocat, which would be necessary to use the sourcedialog plugin.  But getting ckeditor from a CDN works just fine.

So to edit source, we'll just have to go to zenphoto for now.
