transparency problems

yesterday i was trying to make an animated icon. to make it so that only the picture would be animated, i tried to make a transparent icon with text on it so after i animated the picture part, i could just copy and paste that into the transparent icon with the text. except when i tried to save the transparent icon with the text, it said there was a lack of information or something, & saved it as a merged .. something. i don't remember. i use psp8. can you not save transparent things with just a little bit of text on it?

thanx in advance.
