John,
I can't seen anything wrong with the photos on my pbase account, nor yours. The only thing I can think of, is you have managed to find a way to direct link to images on a specific server - rather than the general URL - which would continue to work even if they take a server offline.
E.g. your avatar URL is this:
Code:
http://i2.pbase.com/u39/jaydoubleu/upload/39402776.bench.jpg
Wheras I'd use the following URL for the same image
Code:
http://www.pbase.com/jaydoubleu/image/39402776.jpg
Which if I'm correct shoudl show up below:
I reckon to access the image URL you are right click at the image and taking the URL from the properties - wheas you should be taking the "URL" out of the browser address bar - and adding ".jpg" on the end.
That way - its server independent.
Hope thats helps. Shout again if that doesn't make sense.
