Some .png files are not showing

The website is wwww.barswithlegs.co.uk

on the top right there should be a picture link, its a png file. it was working fine and then one day i noticed it had gone. I just cant seem to get it to display!

Please help,
Cheers.

Do you have AdBlock installed? When I view the page with it turned on the call to the image results in:



Turning off AdBlock and it works fine. Seeing as it's being served from the site itself I guess it might simply be down to the filename: ad2.png

Try changing the filename.
