Here, I made a video and uploaded it to youtube that shows what I'm doing. Hopefully someone can spot the error that I am making. Thank you to anyone who can help me, this has been very frustrating and I just want to figure out how the heck to do this!

The reason I have been using MSPaint is because when I paste image #1 on top of image #2 in Paint.Net, Image #1 maintains the checkerboard background around it. So I had to open up the combined image in another program to "confirm" that the checkerboard was in fact transparent, but unfortunately it's not. When I combine the images in Paint.Net, and then open the file using Windows Photo Viewer, the region that appears as checkerboard in Paint.net shows up as white. Basically, it's checkerboard in Paint.Net, and white everywhere else. And I don't know what to do to fix it.

Yes, I am pasting the image over the top of another image in MSPaint. Whenever I look at the image in Paint.Net, the background is checkerboard, but when I look at it in MSPaint, the background is white.

Hello, I am having some trouble using the Magic Wand method to make an image's background transparent. What I have done: -Select Magic Wand -Put tolerance to 0% -Click on the area I want to make transparent. The area is outlined. -Press Delete key -The outlined area turns to checkerboard -Save as PNG I then select all, and copy the image. And then paste it over the top of another image. But the background that I previously made transparent is still white. Am I doing something wrong? This is quite frustrating.
