Look, the situation…
We parsed some data and grouped it in CSV-file. For example, we parsed listings of several categories of goods(like milk, bread, fruits and etc.). We attached ZIP-file with category images (20). Next, we imported the data, now we have approximately 5 listings of milk, 3 of bread, 10 of fruits and etc. We used only 5 images from 20 (1 for milk category, 1 for bread, 1 for fruits). So 5 images are already in Media Database. Then we parsed new data again and we need to import it. We attached the same ZIP-file with 20 images. We imported new listings with the same categories (milk, bread, fruits). Now we need a plugin not to duplicate the images but to choose from the existing ones in Media Database.
I believe, that now the situation is more clear.
