Require *Genuine* Help

[David]

This request has been posted B4 yet I received replies from idiots only that 
gave no help whatsoever.

Whenever I try to view JPG's or JPEG's I get the following response:-

Unable to display file.

The JPG file could not be decoded.

C:\NEWSROVER\!!!SP4.JPEG

OK

The fault cannot be that the file is too old because it was posted in 
October, *and* other JPG's/JPEG's are being displayed, namely spam 
containing JPEGs of unbelievably fat women. Do I have to make adjustments to 
get the JPG's I wish to view?

Your help would be appreciated, David.
