images not resizinging on product page

I have purchased the gold cart plug for the mazine theme and installed it if that helps with my question. On the products page i have set it to show all products but on the mazine live demo the full product image fits inside the dimensions applied ( Default Product Thumbnail Size: Width:151 Height:173 ) and when you enter that product the image enlarges to set dimensions ( Single Product Image Size: Width:302 Height:341 ) .Now when i do it the Single Product Image is okay but the front store page with all products on it the images are not proportional ,they show up with parts missing,also i noticed that the product images don’t seem to in the C:\EasyPHP-5.3.9\www\wordpress\wp-content\uploads\wpsc\product_images\thumbnails folder but are in C:\EasyPHP-5.3.9\www\wordpress\wp-content\uploads\20125 folder
