K new modularity problem with repeater.png

My site is here http://www.bikinis-canada.com
I wanted to make the transparent grey box light pink, made a 1px by 1px transparent png and uploaded to replace the original and now nothing shows up. I tried to upload the original and its still not showing up. Code was not touched at all, just the png file was changed.
Any ideas on what is wrong? Tested in IE, safari and iphone and still gone.
Thanks!
