If you are happy to use a command line tool, you can do it with an old command utility called trunc.exe. You can still download it from Google code archives (run the usual antivirus scans)
Google Code Archive - Long-term storage for Google Code Project Hosting.

Basically, the command usage (which you can check by using trunc /? in a command box) is :
trunc.exe filename filesize (in bytes)
trunc.exe filename size
trunc.exe "alp ha.JPG" 1

this will "truncate" the file called "alp ha.JPG" to "1" byte in size (you can even change it to 0).
I would copy the trunc.exe to the folder containing all the .JPG files and create a batch file there (say reduceJPG.bat) to truncate all .JPGs to 1 byte like so:

contents of
FOR %%A IN (*.JPG) DO trunc.exe "%%A" 1
this will truncate all the files named *.jpg in that particular folder to 1 byte.

As this tool is quite powerful , before you begin, make sure you have a proper backup plan (just in case) to try your procedure on a test folder, as the batch file will truncate all the specified files without stopping .

So create any testfolder with

some sample .jpg files

and run the batch file there first, to see how it works.

PN: trunc.exe can also be used to pad files to new larger sizes as well

Hope that helps.
That's the program I remember using a long time ago. Thank you. I've downloaded it. It will come in handy after I've done all the processing I need to do.Setting up the folder for my next download session. Thank you.

Now all I need is the crystal ball to identify duplicate downloads in real time :) The problem being an artist might have 20 pictures which all have the same name when downloading, and the download is saving them as artist.jpg, artist (1).jpg etc. Although, when I run Duplicate Cleaner Pro. It does an excellent job at sorting out the duplicate, although quite a hands on process. So let me try to set this all up together and see how it goes. Thank you.

Thank you to all the contributors to this thread. I think I have the solution to all my problems except the biggest one, downloading duplicate files. I don't see any possible solution to this. So be it. Really appreciate the help provided. Thanks.

You said that you want to prevent files from being downloaded, right?
What is forcing you to re-download the files?
Because I cannot remember the files I've downloaded before. Some yes. But most no, or not sure.

I think I can understand what you're trying to do, Irfanview has a conversion facility where the user can select the file (re)size by dimensions, MPs or % of original. You mightn't be able to get them down to 1 byte, but as low as possible.

Alternatively, create a shortcut link to each of the images (usually about 2KB in size)
Thanks for the tip about IRFANVIEW. I don't think it will be useful for the purpose I'm needing. But it looks a lot better than all the wimpy standard graphics viewers which come with Windows. I just need to find out how to set it up as my main graphics viewer and editor.

If anyone has any suggestions to replace Duplicate Cleaner Pro (which is a tad "clunky") with something smoother or better. I'd be open to any suggestions. But it does it's job well.
