Hello newsgroup,

I got to this group from the public German Excel group, where my
question could not be answered. I hope this is the correct place. :-)

This is my situation:
I have an Excel UserForm where I display a low-resolution image. After a
user click on the image, I want the picture to "zoom in", i.e. I want to
replace the low-resolution image with a small portion of a
high-resolution image showing more details.

Any hints on how this can be achieved with some API function?

Thank you very much!
Jens
