Just a thought. Any Windows machine that you can browse the Internet from, should have "Paint" or "MSPaint" in the Accessories folder. You can open your pic, click "Image", then "Stretch/Skew" and use 50 or 60%. I always use Save as and add an "a" to the file name, to preserve the original. I doubt that you will see a difference, and the new file will be in the 100's of KB, instead of MB. Give it a try.
