i have a little problem (but extremely boring...)with the thumbnails under pro pack: i ve made a character and i replaced the .png file (originaly created by poser) i made a render of my figure in .pict format (600x600) reduced it in 91x91 and converted it in .png format then i renamed it correctly(the same name as the cr2) but then i only have a light grey circle on the thumbnail and no thumbnail of mine anymore!!!! if someone already had a problem like that please help me!!

No, if there's an alpha channel in the PNG thumbnail, don't delete it. When Pro Pack can't find an alpha channel, for some idiotic reason it assumes by default that the entire thumbnail is completely transparent. From the looks of the image you posted, I'm guessing that your converted PNGs don't have alpha channels. So load them into your paint program and give them some.

This procedure will work just fine: 1.) Create the image you want with Poser Pro Pack and render. 2.) Save as PNG 3.) Work on the image in PhotoShop or another image program. Get it the way you want 4.) Reduce to 91x91 pixels 5.) Copy the thumb to your library.

I had the exactly the same problem some days ago. Solved by using the free PoserExplorer P3DO with the free plugin and converted the .png's to .rsr and back to .png. Worked perfectly!

You can make your .png any size but about 120 pixels wide by any length seems to be the best
