I am creating a file to load products into the cart by using the import file option.

The Image parameter for the Image field is the path to the image - (I want to use the images in the Image folder of the server).

But when I look at the image folder on the server, there are many versions of the image... one is the original image as I created it on my PC - for example; "15-25-reinforced-300.jpg".  Then there are 5 more "versions" of the same image file - for example "15-25-reinforced-300_26r1j4zj.jpg" (the other 4 are similar - just the jumble of letters and numbers after the "_" underscore symbol is different.

Why are those extra versions of the image file there?
