GIMP - adding watermark to multiple images

[JanN]

I have a whole bunch of photos clicked during the weekend (office trip ) and I need to add some text on the images .. simple stuff like the location, and date.
There are about 190-200 images. I just wanted to know if there's any option for adding batch watermark . I am using GIMP 2.6.

Thanks.

Gimp batch operations. You'll have to be comfortable using the command line. There are some other good tutorials there too that can spell this out much better than we could here.

What operating system? If you are on Linux, you may find using ImageMagick (again command-line... so perfect for writing scripts and one-liners that do clever things) is a good solution.

I used to use it to create thumbnails of my images (before I moved to uploading to Flickr to accomplish the same) but I am sure it has image merging options too.

Best start a new thread for that as this one is concentrating on The Gimp (this would be the right area to post it in though).

Ooops! I forgot to mention the OS. I'm on Ubuntu.
I'll have a look at ImageMagic as well..

Thanks

It looks like composite might be the particular ImageMagick command you want. See:

ImageMagick: Command-line Tools: Composite

You could use this to, for example, overlay your logo on top of all images in a directory. The shell script (which you could then run as a simple command) would be something like:

for image in *.jpg; do
 composite -compose atop -geometry -13-17 logo.png $image $image.watermark.jpg
done

You could also chain some other processes into the logic, such as also resizing the final version down to no longer than 740px on the longest side (for DPS), putting a copy of the original and watermarked images into suitable areas on a backup directory or using different versions of the logo depending on the size of the original.

Yes I did

Googled for batch watermark GIMP, and found this

ImageMagic is good too.. started experimenting.
