Twidroid avatars stored on sd card??

[OLDDAWG]

I need some help. I downloaded all my photos today from my Droid. I got my photos and about 70 avatars of people that I had read a tweet from on Twidroid. Some of these are on the SD card 5 or 6 times. I have tried to find how they got there but no luck. I did not knowingly set up to save these. How do I stop this and how do I delete from my SD card? Thanks for any help given.

There are setting in Twidroid to use the SD card. There is also an option to clear cache of avatars.
