O.P. My mum rang me this morning ready to throw her iMac away... She has had an ongoing problem with photos being sent which are somehow getting corrupted missing parts, grey and blue banding, etc. I was actually able to replicate this on my own PC using my dotmac account, so it's not her computer and it's not the image and it's not Mail. It must be something to do with the servers at Apple. Has anybody else experienced this? I haven't found much in the big webland. I suspect it is caused by slow upload speeds, and the connection timing out or something.
