What browser might you be using?

Dar_Win it shouldnt show as an X if he had the crappiest computer in the world, it should still slow, just not great. Although it could be your connection if it's REALLY, REALLY, mind-numbingly, cow-grazingly slow it will just time out when trying to reach the host to download the pic.
If you're on IE, try going to Tools / Internet Options... then go to the Advanced Tab and click Restore Defaults. Reload your browser (shouldnt be neccessary to reboot your pc, unless it asks you to) then try again. If it still shows them as an X let me know.

Maybe tonight we'll fly so far away... We'll be lost before the dawn...
