Save a JPEG returned from EZTWAIN

Trying to save a scanned image as a JPEG file. I acquire the image using EZ TWAIN dll and get back a handle to a DIB. How do I take this handle to the DIB and save it to a JPEG file using the sample code:

http://www.vbaccelerator.com/codelib/gfx/vbjpeg.htm

I been trying to use the SAVEJPG method of the cDIBSECTION class but can't seem to figure out how to convert the handle to a DIB to a cDIBSECTION object so that I can pass that to the SAVEJPG method.

Also looked at FreeImage:
http://freeimage.sourceforge.net/download.html
All example in C++, couldn't figure them out. Need VB code examples

The 'Pro' version of EZTwain (http://www.dosadi.com/eztwain3.htm) is commercial, but can load & save JPEG files (and TIFF, PNG, etc.) - It uses the IJG's LibJpeg which is freely available.
