Hello MaxD, I have recently purchased your extension and I am having a problem. In my site I have many GBs of images in the image folder. I have noticed that Lightning creates a dir called image/cache and makes copies of all my images resulting in my server running out of space and being unable to run the extension.
I don't know why it is good to cache images on the server but I need to be able to switch it off. Please respond asap because it is really important.
Note: Pregeneration is off.
