Jpeg files and Win32Lib

Hi All.  
I've been looking for a simple way of loading Jpeg's into a Win32Lib Windows
program.
So far I've looked at all the contributions under the search term 'jpg' and
'jpeg', but none of them really provides a sensible option.  ie they mainly are
convertors into BMP's on disk - not really a great idea for something that might
run from CD!!!

The CXImage DLL wrapper comes close to what my requirements are, but it does not
produce anything I can use with Win32Lib directly (ie a DIB in the same format
(and I thought DIB's were a Standard!!!!))

Has anyone (Mic!) enhanced that wrapper, or can anyone point me in the right
direction as how to get a 'DIB' in the form {pixels, width, height, bpp} into a
'DIB' that can be displayed using CopyBlt, DrawBitmap, etc ????

I don't really want to be doing an execute of another executable (a la Al Getz's
stuff), or using Tommy's Win32DIB (at the moment - though it's really, really
good and should be incorporated into win32lib IMHO ;) ), but would prefer to have
the simplicity of the cximage option - a single DLL, a simple wrapper and only a
couple of calls.

I'm sure I can't be alone in this request - nowadays Jpeg's are standard, as are
Png's, and BMP's are just cumbersome.  Let's get something that can work with
these standards.

Thanks in advance.
