Hey guys, just wanted to let you know that Interfacelift.com, which is a great source for backgrounds (mostly nature ones, but with custom-made abstract ones, as well) have added an 800x480 size to their download list, so you no longer need to download and THEN crop the image.
I spoke with Jeff recently at InterFacelift and expressed interest for this. He said he would start adding the option on new images and see how the traffic was.
Just hit up www.interfacelift.com and browse the images. I think currently only the most recent 2 images are sized, but you can download it straight to your tablet.
I'm not affiliated in any way, just wanted to let you guys know.
