I'm repeating myself for the third time in one of your posts Matt, but here goes again.

Its the links your using .You need to use the
address link when you click properties on your pictures at your pbase site or open the picture on your site ,copy the address from the ad bar and add .jpeg to the end of it ..Don't use the
location link which is what your using .
http: //i.pbase.com/o6/92/401592/1/77812404.U3J0pGWv.soapbubman.jpg .Those links apparently change when they move stuff around on there servers so sometimes they will work and other times they won't . Thats roughly the explanation i got from pbase when i was having the same problem .
Your links should look something like this
