Hey I figured out how to get rid of the stretched picture on the events module: so if you go to edit modules, then click edit on the events modules scroll through the code til you get to the user-thumbnailUrl change the dimensions to 0px by 0px. Or just copy/paste this piece of code in place of the similar code that was in there (so don't delete all the code - just replace this part):

<img src="<fx:user-thumbnailUrl/>" style="width: 0px; height: 0px;" />

There is also a great tutorial from Michael of RocksRocksRocks about changing that picture if you don't want to remove it all together.

Good luck!
