re: Yeah, I've been trying and no luck.
Your html must be right since it showed me a red X. :)
{img src="your url"} use <> instead of {}
If they were too big you wouldn't have been able to upload them to your tiki files so no you don't need to know the file size. Just do basically the same thing you did at tiki file at image galleries. If you have a problem let me know
