Weird! It looks like the image they're trying to request is this one (I just changed the domain):

That definitely wouldn't fit in a 250 x 250 box though!

I've spotted a similar AdSense ads on my own blog this afternoon:

strange.

Broken for me too – on both pages... But I've seen worse :D

ive spotted it early today..

this is a qeird thing....

If you click on it it returns a "not found" error within the adsense iframe (no wait, not "if you click on it" – "when I clicked on it" because I wanted that toolbar :-)). Want a screenshot (how can I post one)?

I think something it wrong with images all round google. My Google Desktop Sidebar won't show icons along side the options for gadets to install.

It seems that it's already been fixed. They must hire full time people to scan blogs like this for errors :)

I had a broken 200x200 in mine (http://sojoe.info/2006/12/13/firefox-toolbar-finally-catches-up/), but after a refresh, it came up fine.
