Hi Mechta
Where do I find the tool which allows me to limit the size to 640pixels please?
In Photobucket, if you click on "more options" just underneath the green "Upload Images and Videos" box, you'll see a selection of sizes that you can set. It won't increase the size of your image but it will reduce large images to the specified sizes.
Incidentally your 3-view has now shrunk to a very small image!
