I still see the same type of images, too.
ISP: hmm, not sure, maybe KDDI, but I don't remember seeing this type of thing on other pages which block hotlinking
No software firewall running (using W2K & IE6SP1)
Not connecting through a proxy server
Refreshing the home page doesn't make it go away, but clicking the forums page does. (If I go directly to the /forums/ url after clearing cache, I don't get teh same problem. It appears it only shows up if I go to 'www.able2know.com', and only if I go there before going anywhere else on the site)
I've never remembered to post this coz I only see it when my cache is empty.
I can clear cache & check it out on my home PC tonight, & I'll let you know if it looks the same from there.
Let me know if you need any further info..
