This is how to organise product photos (Windows CMD method)
Best you watch this video first on how it is done 
First we have a batch file with the bellow, we called ours rename.bat :
ECHO off FOR /F "tokens=* USEBACKQ" %%F IN (`zbarimg --raw -D -q %1`) DO ( SET fullbarcode=%%F ) ECHO Full barcode: %fullbarcode% ECHO ON rename %1 %fullbarcode%.jpg
Then we use this command to trigger the action, this action can be copied and pasted in the CMD or powershell. Make sure you are in the bin folder of zBar application.
for /f “tokens=*” %a in ('dir /b *.jpg') do rename.bat %a
The current limitation, means that the photos must all be in the bit folder.
The application you need is below, including the IOS app for the Barcode capture. As well as the batch file used.
