Causes Redirects

I installed the plugin and it creates redirects from the gravatar image to the alphabet letter image, so then I have a bunch of redirects, which does do well on the speed tests either.

I thought this happened because I was keeping the actual gravatar available to people who have them with the mystery man option and using letters for those that don’t, but then I switched to a blank space instead of the mystery man, and it still seems to be happening.

Is there any fix for those, so that I can use the plugin, but not have the redirects to the letter images?

Thank you very much, I love the look of the plugin in my comments and would love to use it.
