Mark,

Why not just use a Webbrowser control on a form to display the image?

>I've found that when using scrollbars to display a large object (image) in a viewport, there seem to be some undocumented maximums imposed. For example, the largest image height I can use is about 2400 pixels. Anything on an image taller than that (assuming image TOP=1 on form) is clipped from the bottom of the image with no warnings or error messages.

>Can somebody fill me in on what the rules are here and what's really going on? I don't think this is the famous (disappearing) scrollbars bug. It seems to be an OS limitation or something.
