I was wondering about this too, I was trying to send headshots via craigslist taken from my phone, and their limit is 150k, and my pics are 500k+, but when I save them on my computer their less than 40k...
I had to actually log onto facebook Real version (not mobile) through the phone, find the image, and somehow find a way to save the picture (from facebook its really hard, find the picture on the data intensive version, zoom in, load it, save address, paste address, save image, etc)
