Recently I started working with Q2A and I found that avatars are stored into database with no option to change this. I know, storing avatars into DB makes it easy to manage them (and dynamically change size), but in my opinion, performance is most important thing. Showing avatars from MySQL, rather than filesystem, require a huge of memory and time for processing (for each displayed image, the server will send an additional SQL query and PHP should process image).
I don’t know why you choose to store images in DB, but for version 1.7 I want an option which will change this behavior. So, what is the probability that this will come true? Wait for a new version or I shliud try to change it yourself?
