jQuery pngFix problem

I tried to use a jquery pngFix but it didn't work... i was angry when i tried every variation.
I found the wrong line in the jquery selector.

I had to change this line

......find("img[@src$=.png]")......

to this

......find("img[src$='.png']")......

I used jquery 1.3.1 and jquery-ui-personalized-1.6rc6.min.js

so If you don't know why doesn't it work, try this one :)
