[Topic decapped - please do not yell here]
have used this plugin for a number of sites and while it does the job there is one aspect that is a strong negative.
For some reason this plugin generates tens if not hundreds of thousands of files on the server that has caused me some grief with my hosting service (Bluehost) to the point where they advised they may have to disable my account.
What I find particularly troublesome is that there is no mention in the plugin settings or the documentation that this proliferation of files may occur. Nor is there any mention of which settings may trigger this. It wasn't until Bluehost notified me of the problem that I was aware of this issue.
Due to these issues I have deleted the plugin from all the websites I maintain.
NOTE TO DEVELOPER:
I think it would be in everyones best interest if you clearly identified which settings caused this problem and also put warnings in the plugin settings screen so that this problem can be avoided. It really does tarnish what otherwise is an excellent plugin.
