I noticed that Message-ID: <7c********************@comcast.com> from DH
contained the following:
I have a "file upload form" that works OK, but I have been unsuccessful
in my attempt to also resize the uploaded .JPG (if it is too wide),
over-writing the original .JPG, and then create and save a thumbnail.jpg
... all at the same time. Links to a working example would be
appreciated.
I've got some code that needs tidying up, but you are welcome to have a
look.
