Not a problem, just curious; When I go to 'Insert Image' 'From URL', if I don't uncheck the 'Retrieve Remote file and reference locally' box and upload I get 'error: Remote file is too large'. When I uncheck that, the pic loads fine. What is that 'Retrieve Remote file and reference locally' trying to do ?
You have the option of downloading the file from the remote URL (Picasa, Webshots, Facebook, etc.) and storing it within vftt.org. Then, when someone loads you post, they get the photo from vftt.org, not from Picasa, et. Al. This of course duplicates the files and uses up space on vftt.org, so there is a limit of how big a file you can do this with.
Personally I think you should link to the remote site via standard [img]insert-link-to-photo.jpg[/img].
