Whenever I download an image from my iPod touch to my MacBook through Cyberduck, Transmit, MacFusion, or any other sftp program, the images I copy to my mac are always 100% transparent, no mater what the image is. Themes, app images, system images, everything, they're ALWAYS transparent. It's very, very, very annoying to email files, one at a time, to and from my iDevices. Is there any fix for this? I've got iPod touch 2g, MB model, 4.2.1 os, jailbroken with redsnow.
