GIMP is the common default image manipulation tool bundled with a lot of distros. If you don’t need one often except for some cropping of images, or resizing, then you probably don’t know how to do a lot of things with this tool. At least in my case that is true. If you upload your images online, it would be good to have a watermark on them so that people would know those are yours and even if they are used by someone else (through hotlinking, etc.) your name is there. I’ve been taking quite a number of pictures as of late and so this watermarking business has come to mind.
There are a number of techniques you could try out to put a watermark on your images. Here are two techniques:
- From Deviantart user, fence-post: Simple Watermarking in GIMP
- From Flickr user, Travisatwork
With fence-post’s guide, the basic instructions boil down to:
- Make a new layer which will contain your name (or whatever it is you want to use for watermarking the image).
- Apply the Xach Effect on it, which would give it highlight and shadow.
- After applying that effect, you need to change the opacity of the layers so that the watermark will be less opaque.
- Flatten the image then save the file.
Fence-post’s guide has images so even if you are using a different version of GIMP, you will still have an idea of what it’s supposed to look like.
This is a sample of the watermark from fence-post’s tutorial:

The tutorial from Travisatwork is very straightforward.
- Make a new text layer with the text of your choice.
- Apply the emboss effect on the layer of text.
- Lessen the opacity of the layer of text.
- Flatten the image and save it.
It doesn’t really need the screenshots because that’s how straightforward it is. Though, of course, if you’re a GIMP newbie, you might find it weird to just keep on pressing keyboard shortcuts.

The one from fence-post appears to be more 3-d. It depends on what kind of watermark you really want. I hope these will help you be more comfortable using GIMP. :)
