Google PageSpeed pointed out that the images I had set to 125px were originally 306px. This patch makes the widget use the "thumbnail" size for the source image instead of "low_resolution" when the image size is 150px or smaller. This will save decent amount of bandwidth per picture, my PageSpeed went from 85/100 to 90/100 with just this change.
