Anyone use host monster?

Im in host monster trying to upload a new image for my skin header.

I took old image into paint, redid it, reloaded it back into the images files and good to go.

on the right side of the folder in shows a “type” column, under that column by every picture it says “image/x-generic”

Expect for the image i loaded back into that i edited. It shows “text/x-generic”

Why is it doing this and how do i get it to a image/x-generic?
