Corel is giving away free copies of Paintshop Pro 10

I bought this version two years ago and like it more than 11 or 12.
Lot's of texture and graphics editing tools in this software. Supports many file formats including 16 bit PNG with alpha transparencies needed for Uru. Create alpha masks from grayscale textures to make lens flares that fade.
Takes many plug-ins like flaming pear and Nvidia DDS utilities.
Seamless texture tool blends image edges so photo textures can be tiled.
Highpass filter takes the brights and darks out of photo textures so they tile without nagging repeating spots due to flash.
Get it!
