VB Game RPG

I am learning VB and I am trying to make my first RPG. However, I have made 3 sprits, all of a front view. When Trying to make the image background transparent, using animagic, when the images move they flicker a black background... Very annoying. How can this be fixed and is there and easier way to make the images background transparent???

Can anyone help me?:(

I don't know what you are using, but it seems to lack a backbuffer
go to www.ur.co.nz there are some good bitblt tutorials that give you all the code and theory you need.
