NO homepage feature area image recommended size!

I realize this probably has a very simple solution, but I can't seem to figure it out. My Bizway homepage feature area images are distorted. There is NO recommended size for the images listed, and the size I found suggested in another forum (130 x 265) does NOT help.

Please tell me, what is the correct size??

Thanks!

 

The recommended size in feature area image is
height: 130px;
width: 265px;
