Facebook Irritations - Failed upload of JPG

So there's this JPG file that I want to upload to my Facebook page.  But it will not upload.  I try converting it to a GIF.  But it will not upload.  I try taking a screen shot of the file as sharing seems to be blocked, to create a new JPG.  But it will not upload.  I try all versions of the file in IE8, Firefox and Chrome.  But they will not upload.  This has happened a few times before even with unedited photos I have taken.  Why?  Anyway I'm going to try and upload the file to this blog.
