I'm not aware of a way that allows you to specify a file size, but you can use convert from media-gfx/imagemagick to re-compress and/or resize the files. For example: convert -quality 50 in.jpg out.jpg convert -resize 1000 in.jpg out.jpg The last command makes the image 1000px wide and sets the height automatically to the right value.
