Actually here a link in worth more than a picture as we can look into the code to get an idea whats happening.
However the image provided shows images in the standard 3 sizes.
Small, medium and large... So it would appear to be working as it should
But that is obviously not what you expect
So answer some more questions
When you hit reply answer the "Posting Tips" questions asked about versions etc
What size images do you have setup for small, medium and large images
What size is the the original uploaded image
Do you have previous _MED and _LRG images already in place for these images
Also again post a link if possible
