I have a large catalog import where the items often refer to a single common image (such as "brand_logo"). When I import the images via CSV parser, if the item refers to the same image file, an incremented duplicate is created.
Example: Using the example files supplied with the module, I modified 2 books to use the same image file, which are imported to
This causes the images directory to balloon to 20 times the size it should be (lots of shared images).
Honestly, what I would prefer to do is to upload the images to the site separately (manually, via FTP etc.) and just import the links to the images, but I haven't figured that one out either.
(The data (files) is not being replicated, just the images are replicated.)
