Hmm, are you sure about the class name? I'd say that on a new layout with
the same HTML 'pad1em' could end up making very little sense. A golden
rule of css is that a classname should reflect what something is, not how
it is _displayed. A more suitable name could be something like
'imagepreview' or the like.

Oh yeah.
(Just make sure the file is a proper image directly after an upload.
Examining extention or mime-type is no good. I'm quite happy to us
getimagesize() for this purpose, as it would return false if it couldn't
interpret a file as an image.)

And to display only files _ending_ in jp(e)g, I'd use
preg_match('/\.jpe?g$/i',$string);
