Feature request from bubach, posted on GitHub Sep 29, 2014
Hi, I'd like to request just generally more settings for how and where images are stored. Possibly even fallback functionality for where to fetch images if not found in main path. One issue I have in particular with the current code base is on this line:
https://github.com/magento/magento2/blob/develop/app/code/Magento/Catalog/Model/Product/Image.php#L5...
Where store ID is set as part of the cache path. In some webshops where you have 10+ stores and literally all the images are identical, it's a huge waste to keep duplicates of every thinkable image size. Not to mention the server strain when clearing the image buffer.
