Yet another unexpected change here to blogger: When you click on an image to enlarge it, you first get a framed, somewhat enlarged image. THEN, if you want to see the full sized image, you have to right click it, select "image" then click that. THEN, when the image comes up with a little + sign on the cursor, you can then click it again, this time (finally) for the full sized screen filling detailed rich image that was the whole point in a 1 MB upload.
All this clicking is making me weary, but it is actually easy to do. Try it on an image here and let me know what you find. Here is a test image.
