Saving transparent
Here is what I do . I like to do pictures I think it is easier to follow.
Here I made one in psp and now I click on the blue bar and copy and paste in animation shop so now I have picture 1
From there I do the following pictures.
After you save it and want to use it again you do have to open it in animation shop and then copy and paste in PSP or you can go to File and down to export into psp and it will bring it over there.
