How to import product image with the magento import tools ?
It’s quite easy, when you know how to fill your import file and put your file in the right directory.

The directory : create if needed a /media/import/ direcory in your magento root file, in my case it’s /home/www/eshop/media/import/
Paths in the import tool are always relative to you media/import directory.

The imported file : on you image or small_image columns, you need to put your file name prefixed by a “/”.

Some examples:
picture file ==> string in the import file
/home/www/eshop/media/import/product1.jpg ==> /product1.jpg
/home/www/eshop/media/import/ProductPage/product1.jpg ==> /ProductPage/product1.jpg

Hope this will help you.
