How do I batch resize pictures for faster upload to Facebook?

[ehtubert]

I like to share photos on Facebook and I’m frequently uploading large numbers of images. Facebook compresses these after the upload, but the upload is still very slow. I am thinking of compressing the image files pre-upload, am am wondering if anyone can recommend an upload tool for Facebook which compresses and optimizes the pictures and batch processes the upload?

Looks like this could do it:

JPEG files are already compressed so you wont gain much by compressing them.

Broadband upload speeds are always far slower than download speeds, so I think you are better starting the upload before going to make a cup of tea or watching a TV program.

in the bottom right of the Facebok page is a help option.

If you look there it has a whole section on uploading photos, see if anything there helps.

ImageMagick is an excellent commandline image editor.
