Click on the individual image to download. The shadowing is not on the tubes. If more than one image is shown in a sample, all the tubes are included in one zip file. The files noted as PSP format [they have a .psp extension instead of .tub] are compatible with Paint Shop Pro versions 5 through 9. Open the psp file in in PSP, then File/Export/Picture Tube. Then name the tube. It's a good idea to use the same name as the psp file.
If you'd like to create your own heart like my original doubled heart tube and the Hearts of Gold tubes, there's a selection tutorial I wrote for them HERE in my PSP Quick Tips/Mini-Tutorials section.
