The gradients come in a zip folder, so unpack the files, then install them here: CProgrammsGimp2.0sharegimp2.0gradients The files are all .ggr files Have fun! n__n
In case you get an empty file: If the .zip file is empty after you unpacked it, please try downloading again! If the problem still remains, send me a note with your email address and I'll send you the brushes unzipped by mail. As to why this may occur: I don't know I tried every way possible (windows and mac) and the brushes were always there, so if it upsets you, send a note to DA and complain about the issue there please. I would be happy if they could fix that bug.
did you try to unzip the file? Normally your PC should already have the ability to unzip a .zip file, but in case it hasn't: you'll need a program like winRAR (or any other free zip program, just google it) to open the file.
