It was my job to take all their photos and rename them based on the date taken, resize them and store them by week ending date. I am working with construction guys and not computer experts so I set up a system with their phones/shared folders to easily allow them to drag/drop new photos into our file-server.
I do not know how to program directly, but found a nice utility called DropIt.
This utility allows me to take a batch/folder of photos and automatically rename them based on metadata I choose and output the results to another folder. I chose date taken. This can rename 500 photos at once to the date taken fast and easy.
I then take the files that have been renamed and reduce them in size using another software called Caesium.

This one allows me to take a folder of photos, specify a new output and I can typically get 90-95% reduction in file size while retaining the quality needed.
Taking it one step further using the folder replication in DropIT, I have it set so when a Superintendent drops photos into the shared folder on the network, it locally replicates those files into a folder on my computer - then drop it scans once and hour - if it finds photos in said folders it will then automatically rename it to the output for me.
The only thing I manually have to do is run Caesium, which is auto configured to scan/pull from the output folders of drop it and place back on the file-server.
My Mondays used to literally be photos all day, doing this manually with the way they showed me - now I can do all photos on all jobs in about 30 minutes (after the initial configuration).
