What do you exactly want to do with your images?
I checked your images and I saw that you uploaded images 200 x 200 px ( actually width varies ).
Now:
At PRODUCT LISTING page you configured images to be 80 x 80, but, if your images is 69 x 200 px, like your clothing2, then it shows as 28 x 80 sized image.
You can see here that image is resized proportionaly.
At PRODUCT INFO page, your images are configured to 200 x 200, but it's displayed as 69 x 200. The same story.
LARGER IMAGE: If you click on larger image - it displays the originaly size of your image: 69 x 200 pixels.
What's the remedy ?
- You should make a model ( background ) of your image ( for example: 600 x 600 px - something what I used in faktor.rs ), then - with PhotoShop or any other program that you use, modify your images - apply them on that model, and save it as new image.
Then you upload your images to server.
They will be proportionaly resized, but you will always have configured sizes ( 80 x 80 and 200 x 200 ) and your larger image will really be larger ( original size 600 x 600 )
- You can also upload three different images ( small one, _MED, and _LRG ). So that zen-cart doesn't have to calculate their sizes ( some guys said that it has influence on the speed of your site )
And....
something else.....
Try to show your images in parts.
For example your clothing2 - you can divide it in one main image and one or two additional images.
It will give you possibility to show more in details.
