Hey. I was just wondering what the maximum size of a bitmap is in pixels. I just tried to create one 600 tall and 20,000 long and microsoft paint almost crashed my computer. Is it too big? Should I just use Adobe Photoshop :-)?

If you can afford it, yes.

The maximum "standard" width (and height) of a Windows .bmp is 32767; however, Photoshop can handle sizes much greater than this, given enough memory.
20000x600x4Bpp equals almost 46MB of data, and I suspect Paint wants it all in physical memory.

If you can't afford Photoshop or another professional image manipulating app maybe you can download trial/demo. Of course this won't help you if you plan to use it for longer time periods.
Or maybe try Gimp? It's free and there's windows port. But I have no idea how it will behave with images of such size.
BTW why do you need image that big?
