Windows Picture & Fax Viewer wont open pics ?

[Andy12437]

I am using WinXP Pro.

Saving pics from the internet i can see thumbnails of them in the folder, i
can click on them and they open in Win Pic & Fax Viewer (as expected).

However, sometimes when i take them from a digital camera, or scan them in,
or alter a picture in paint programs, i lose the thumbnails and when i click
on them, Win Pic & Fax Viewer opens them up, but says 'No preview
available', even though if i right click on the picture and choose 'open
with' - 'Win Pic & Fax Viewer' they open up OK.

Is this a file association problem ?, i have tried right clicking on a pic
file and using the 'open with' option, then clicking on 'open with Win Fax &
Pic Viewer', but that still doesn't make them open up by left clicking on
then.

How do i get Windows Picture & Fax Viewer to open ALL picture formate, i.e.
..JPG, .jpg, .jpeg, .JPEG etc etc.

Cheers
Andy

Further to my last, i have just noticed that a picture which will open up in
a yellow folder won't open when i put it on the desktop ! - what's going on
here ???
