Hi Karen,
if you are talking about the website i just visited (
http://www.labradorsonline.com) then this might not be your problem.
(its not a real link in your profile thats why i am guessing)
I checked some topics and if you really mean the pictures in your users signatures all those i looked at are hosted externally on picture services. So i would guess the problem originates there. (some services do only send thumbnails when there are too many hits on a specific picture in a defined timeframe. Also if no pictures are displayed occasionally the service might be unavailable temporarily. If you look at the sourcelink of the pictures you might be able to check a specific service when this happens so you can check if thats the reason. XOOPS itself does not touch these external linked images.
cheers,
Bender
