Open your photo as is. It needs to be a jpeg. Go to Image>Image Size. Make it 145 pixels x145 pixels (or less, 145 is the max allowed, mine is 108x108) at 72 ppi. Click OK. Go to File>Save for Web. At bottom left, it will indicate JPEG, and a file size below it. Play with the Quality slider on the right (just under the Done button) until the file size goes below 10K. Any quality above 60 still shows as high. Preset should be JPEG High. I have Optimized checked in that box, but nothing else. My own avatar goes down to 9.6K at 81 Quality.
Hope this helped.
