I just added about 8 images and each time your computer said I was awarded 5 or 6 points, but such was not the case. There appears to be a flaw in your computer programming. Why should we keep adding images if we get no longer get any credit?
You get points when you caption or tag an image. Tagging should net 1 and caption is 5. Adding a cover nets 2. If you are not seeing an increase try clearing your browser cache. If that doesn't help might want to try another browser. Final option is it's a new bug you would want to post in the bug forum.
