Problem with virtuemar 2.0 in joomla 2.5??

Hello, I'm having problems with virtuemart items because I can not load the images, the page to load the image comes out as if it were corrupt, you know if there is any problem with this? if I need any hotfix? I have Joomla 2.5 and VirtueMart 2.0 template with hot cosmetics. I leave a picture so you can see what happens. See if you can help me. thanks

Your picture failed to add, reduce size. Did you got 2.5 version from us or you got 1.7 and later updated?

Hi, thanks for your answer. I have downloaded version 2.5 directly. No that's wrong, I upload my images to the folder / images / stories / virtuemart / product but then not let me choose them, just let me choose which had by default in the template. I do something wrong? As I can add images to my products? See if you can help me.
thanks

How do you think you upload images to images/stories/virtuemart/product ???

You can not add pictures to that folder manually , because there must be recodr in database to associate product with image url, so you must add it using vm admin

ok, I've done as you have said and as I get well. thanks
