GUI tool for watermarking photos and other images

Question

Parents asked me if they can watermark their photos. By "watermark" I mean a small signature in a corner.

I made Phatch scenario which they run they need. But it looks like Phatch breaks rotation EXIF tag and scaling is not very advanced too.

So I'm looking for a tool that will allow non-technical people to watermark images. Preferably, with automatic colour picker (it should choose invert colour for watermark).

OS X has a good example -- Bronson Watermarker.

Answer 1

Why not try aPhoto (http://www.acein.cn/p/aphoto). It can help your add watermarks easyly.

Answer 2

You could use gimp for exaample, but there are other tools around, have a look here http://www.youtube.com/watch?v=IIgoiecntM4.
