I am running dnn-yaf and having a problem with the avatar. i have the size set to 100x100 but its showing up at 100x15. I have looked at the css fle and cant find anything. Is there something Im missing?

This is actually a feature, to preserve the correct aspect Ratio of the Image images will have different dimensions otherwise in your case any image would be 100x100 would look distorted. The Only solution would be to Crop the Image to make it fit to 100x100. If you want that i can add that Feature, i already add this for Image Attachments.
