Internet Security Problem

Hi

i made a forum up but a small minority are unable to see any of the pictures i have put on my background etc, im guessing this is there internet secturity settings stopping the page sending and receiving the data for the images from my image host. could/does any one know what settings in the internet security need changing to?

well i dont is there in your problem but if you are using firefox then you must have block images from any website that would have cause the problem.
