I have a long list of images (wallpapers/backgrounds). Just for the sack of argument, let's say that I have 500 images. Can I perform a "bulk" image resizing by selecting all the images and have Gimp perform a resizing?

This is a task likely better suited to a different tool, such as Imagemagick (http://www.imagemagick.org/) convert or mogrify.

My monitor is wide-screen (1370-800 (approximately)). Some of the wallpapers are set to a resolution greater than the monitor size; example XYZ image is set to 1400-900. I want to make all the wallpapers the save size without having to perform the task by selecting one image at a time.

If all the images are in the same directory, and you know for sure that you want all of them to be a certain dimension, say 1370px wide, and they are all JPG files, then you could use the command:

mogrify -path OUTPUT-PATH -resize 1370x *.jpg

That will resize all the .jpg images in the directory to be 1370px wide, maintaining the same aspect ratio, and saving them to the OUTPUT-PATH. If there is already a sub-folder called "output" for instance, then the command would look like:

mogrify -path output -resize 1370x *.jpg

I agree on ImageMagick and use it a lot (usually inside other scripts), but for cases where you want to use GIMP, use David's Batch Processor: http://members.ozemail.com.au/~hodsond/dbp.html It works very well for cases like you describe.
