it looks as though you need to transfer the picture from picasso to your picture folder.
should be easy enough to do if you right click on the picture, on the menu find "save as" it will allow you to find the picture folder and save it in there.
someone has mentioned that sometimes, the pictures need to be changed to a jpg. or a bmap.
or they will be too big for posting on the forum.
if they are too big, then change the pixel amounts down to, I think, it is 600 resolution and then it should be able to be posted.
