e commerce plugin problems please help!!!

hi there, i installed the e commerce plugin which have great features and everything run ok apart from the fact that it can’t display the product images.
the folders are created inside wp_content/uploads the images are uploaded there
but i can’t preview them in browser.
the url is http://www.ginisleather.gr/wp_ecom/
and i think that when wp is trying to read them it goes to the path
https://www.ginisleather.gr/wp_ecom/wp content/uploads/wpsc/product_images/circle.jpg
and not to
http://www.ginisleather.gr/wp_ecom/wp-content/uploads/wpsc/product_images/circle.jpg

how can i change that?
thanks!
