An easy way to make a transparent gradient with gimp using the layers function
For my posting thumbnails i wanted to use a transparent gradient (my pictures should fade from opaque to transparent). And while i like open source and dont have photoshop at home, i thought, that i could do that with gimp. Gimp offers here with its layer masks a simple and effective way to implement this.
This tutorial will show you how to do it.
At the end you can download a sample-xcf (gimp-format) file.
