Feeds doesn't import photos I imported products with the help of feeds via commerce product processor. All products data downloaded correctly except the product photo.

It downloaded from csv file, where there is a full direct path to the picture. At settings of acceptability to this field : photo: URI (field_product_photo:uri) 

Import runs without mistakes, but there is no product photo in a product's description. Which is strange because the file is copied to sites/default/files/ it's saving the origin name, except saving in sites/default/files/images and changing the origin name to sku , as it should be by making this products list by hand-labour.

Can you tell me what am I doing wrong?
Thans for your reply. We've already solved the problem. It was bug in sql in file_managed. The total truncate of the table helped.
