Weeappbackground replacement image??

[Ryaninfg]

New to the forum. Just wondering if there is anyone out there that could take the weeappbackground.png file from any of the wee apps and make it a litte darker?? I have tried many other images from themes but none look good or are too big..

Thanks in advance!

This is the current image I am using as the background. It's a little heavy in size which is slowing down the NC..
