large images

Hi guys and gals. I'm a new member and also a bit of a newbie at VB.NET. I'm working in Visual Basic 2008 Express and I'm having some graphic problems. I won't post any code just yet in case it's a known issue with a known solution (which I suspect it is)... But I'm writing a scrolling list...

I have a large image (PNG: 22,550 x 16,7000) that I need to somehow split into several 256x256 JPG tiles. But when I try to load it into a Bitmap (or Image) object, I keep getting an "Out of Memory Exception" error. So, I was wondering if there is a better way to split an image up? Or is...
