Hi I'm trying to import a really big amount of products to my new magento shop. I have a problem with the import. I have some products that are the same products with only small changes (like the height or width) so I want to use the same images for those products. 

So my csv looks like 

sku    |  image

--------------------------
ABC  | /image1.jpg

--------------------------
DEF  | /image1.jpg 

-------------------------

The problem is that Magento imports only the first image and the second line gives an error "Image doesn't exists" 

What can I do? There is a way to import the same image for multiple products?
