Thanks for the tip
In the new gimp, it’s under filters – batch
Handy option to add file pre/postfixes too ….

Indeed, as Aldo pointed out, imagemagick tools are somehow a little easier to use.
I have this folder with like 200 x14MP pictures, and that’s too much for gimp (or my computer) to handle ;)

That seems overkill for something simple like resizing images :)

Try the imagemagick tools

as for that “other” os, i installed cygwin on vista, installed imagemagick and the mogrify command works splendidly. I resized about 500 images for a digital frame and they look fantastical!

Great, thanks for this. I don’t quite “get” gimp, but managed to batch resize images after finding this post, so thank you.

Sounds nifty. Any idea if this is available for that *other* o/s?

Those two solutions sounded great, but the extension did not work for me at all. Two complex errors came up about something to do with the filenames.

The second, imagemagik, I could not find in the Ubuntu repos, so I’m still looking for a solution to bulk image editing!

Thanks,

Keith

Hi Simone, have a look at the Flickr uploader tools: http://www.flickr.com/tools/

Hi Simone, :)

nice tip… but perhaps this package is only in Heron’s repos?

Anyway, I use imagemagick to perform this operation. Once installed, you can easily make several operations, such as resize. Just type in a terminal (pointing in a folder where the images to be resized are located):
mogrify -resize 1200x1200 *.jpg

This command resizes all the .jpg files (and overwrites them), putting them in a square of 1200×1200 pixels, and keeps the right orientation (landscape or portrait) of the photos. The result is a proper resizing of all the images in a snap.

Hope this can be another useful tip. ;)

Bye,
Aldo
