Upload product images to VirtueMarkt component

Hi!
I tried to upload some jpg imges but it not seem's so that it works.
I can browse for the img, but no upload button is there.
Then I have uploaded theme via FTP to the same directory where all the other product imges are,
but they don't appear there when I try to select a new img by the component. Am I doing something wrong?
Can you please help me with that?

If you wanted to upload product images , you go to product editor and you have tab where you can upload images. You can not just copy them. Go to youtube and search "virtuemart upload product images" that is very common thing.
