hi, everyone
I have a question.
I want to draw two images on one panel, and when I save it I want to unite two images and save as one image. How can I do that?
If you have source code, please email to me.

Hmmmm... not sure exactly what you want... when you say "unite" do you mean you want to save both the images next to each other in one file, or do you mean you want to merge the images into a morphed image? I can show you the first... the second is a bit harder...

I have some code lying around that saves images... I messed around with it some to load images and then save a new image of those two... it's kind of hacked together, but it should give you some idea on what to do...

If you need any help with the code, or have any further questions, please post...
