my site is
I only have a couple of items up to play with features atm.
I find some of my images are elongated on occasion.
Let me sum up...

If you click on BDSM Equipment
The top category image is fine. Note that Clothing and Bondage(the same image as the top category image) are both fine.
Now click on Clothing. See how it stretches.

So it is not the images being the wrong size. This tends to happen with other images in this way in other parts of the site like OMG how embarrassing the A.T. product list. I really need to pick another two items to test with LOL.

Any help and understanding for subject matter would be greatly appropriated.
