You can open your .psp files in Paint Shop Pro and Save As: and select Photoshop (*.psd) in the Save As Type: to retain your layers (or do a batch conversion). As for the .tub files hmmmmm I know Corel Photo-Paint (as well as other programs) has the equivalent to PSP's picture tubes. In Corel Photo-Paint it's the image sprayer. I am not sure you can convert the picture tube (.tub) files (but I might be wrong ... been known to happen). Photoshop does have a "define brush" and "define pattern" but it's not the same as the picture tube or image sprayer.
