switch to picasa. The link for the image has a portion near the end that is 's' followed by the size in pixels.
If the image I want to put here is:
https://lh6.googleusercontent.com/-x...1/IMG_4327.JPG
that s731 is the size. I simply change it to s500 and blam! it's reduced to the exact size I want to present in the thread.
