Problem uploading a specific image

I uploaded a jpg file to the media library. the file seems to have been uploaded but it appears only as a gray rectangle next to the other pictures. when i try to use it as a logo it doesn’t work. when i go in to the edit image option i can edit the image but after i save the edit nothing changes with the rectangle.
other pics upload just fine.

Any ideas what is the problem and how do i fix it?

thank you.
