One of my favorite features of Photoshop if the feature "Save for web". Its a nice tool to optimize your image for the web. You can basically choose file format, compression, number of colors and see the results of the optimization in a preview image.
After installation the plugin becomes available in the file menu. The plugin offers the same functions as the Photoshop one:
Installation on Windows
On Windows you just extract the .exe file of the plugin into the plugin directory of Gimp:
Installation on Linux
After extraction of the archive on Linux the installation is done in three simple steps:
./configure make make install
However there where a few problems with that. The
configure script exited with an error message:
configure: error: Package requirements (gimp-2.0 >= 2.3.0 gimpui-2.0 >= 2.3.0) were not met: No package 'gimp-2.0' found No package 'gimpui-2.0' found
This looks like Gimp could not be found, but thats not true. Actually you need the
gimp2.0-dev package installed:
sudo apt-get install gimp2.0-dev intltool
In my case it also needed the package
intltool. After that the installation steps went without no further errors.
