1. i upload images to import/media folder (example: new.jpg)
2. upload product using csv file and contaning correct image file name
3. no errors when uploading, image attaches to correct product, but image is now renamed to like new_01.jpg
why does this occur, its getting my server hard drive space filled up quickly. am i doing something wrong? please help, thanks in advance.
I think. it's something to do with the product upload module you are using. That might be changing the filenames. On a side note, make sure you are uploading web standard images not the hi-res ones.
By default Magento will avoid to override images. If you upload an image with the same name, Magento will add _01 (or _02, 3, 4, etc).
