Hmm I did get this solved in this thread.. here is the
LINKY
viet4777 provides the file as well. What I like about his solution is that in your FB backend, you can set what your parameters are for images. I set mine to 500 x 500 and bam all these humongouse images they were linking were reduced proportionally in the threads. It does not fix old linked images, just the images that are linked or uploaded after you have either ftp'd or edited this file. Just read the thread at that linky and it will make sense..
Good luck!
