GIMP vs Adobe Photoshop
First of all a copyright word. Generally photos and other graphics on the web are property of their owners, and copyright is assumed when they are put on the web. However, I give permission to anyone to reproduce any of the images on this page, provided they do not charge royalties themselves. In fact I think that the first picture is a real nice tilable desktop image for any linux system.
In case you have a poor quality connection I have not reproduced the original image, which takes 57.6 kb of space, but rather the image to the left. If you wish to see the high-quality image, you'll need to have Javascript enabled, and click on the image to the left.
This next picture is the same photo saved at a 50% quality level under the GIMP. This takes up only 10.3 kb of bandwidth on the web, a savings of over 80% in critical web bandwidth. Notice that there is no appreciable decrease in quality.
Now the original image was loaded into Adobe Photoshop 5.5 and saved optimized to take up the least amount of space. Despite being set for the poorest overall quality, the image to the left saved from Adobe Photoshop takes up 12.5 kb of bandwidth, a full 20% more than the much higher quality GIMP image above. And it is blotchy with noticeable loss of detail.
But what about the web-optimization capability of Photoshop?

The free program GIMP is one of the more compelling reasons to purchase linux. For help in using the GIMP, please consult the following resources:

  • In the future I shall be publishing my own GIMP help right here at this site, to cover a few FAQs.
