奇怪的白色图像边框W /标志

I am trying to load an image using css styling and I have a red ridge border around it, but for some reason when I use css instead of html I get a odd small white border on the inside of the red ridge border with a white logo in the top left hand corner the little logo could be a tiny monitor I don't know how else to describe it. Does anyone know what is going on? I have other images loaded the same way with no problem. I am trying to load an image using css styling
