Barbara Jay if you want to make your image transparent. Here's a good starter Google search term- paint shop pro how to make an image transparent. I used paint shop pro because it came off the the top of my head.
Instead of using paint shop pro just substitute it for your graphics program such as photoshop how to make an image transparent. A lot of times it helps to write the version too like photoshop X4 how to make an image transparent.
Here's an example search I did using Google Images- https://www.google.com/search?q=pain...OZOQ8wTDuIDADA
I hope that wasn't confusing.
You will want to save your image as a PNG to make a nice transparent background. Most digi stamps are PNG.
