In logs i found this
media/catalog/product/cache/1/thumbnail/800x800/9df78eab33525d08d6e5fb8d27136e95 /p/a/_lindt_2132.jpg
it's an old image.
I checked in: var/cache the cache is deleted and rewrite correctly.
Does Magento write the information of image in db? Is there a way to delete definition the old image?
Why are there old images in /media/tmp/catalog/product/
Thanks
