The subject for your plea should not be "Shapes" since you are asking about how to do something with a particular package called "Photoimpact XL"
If I am wrong, and you are wondering how to do those same sort of actions with other software, such as with the free "XnView" package then I, or somebody else, might be able to help you.
But you weren't asking for something else to do that. You said "I have the appropriate software such as Photoimpact XL"
Sounds to me like you only need to read the documentation (like the Help) that should be with that software. Are you sure that your software can do what you want?
I want to make a bubble with my granddaughters face inside and no background, ie., page etc. How can I cut out the bubble and just move that? I have the appropriate software such as Photoimpact XL. I can't for the life of me, figure out how to put pictures into different shapes and just utilize that shape.
