Store Certifications and get a custom URL for each.

Hello,

I hope you're doing well. I run an online course through Zoom, and upon completion, I provide my students with certifications in PNG/JPG format. I'm seeking advice on how to upload multiple certifications onto my website and generate unique URLs for each certificate. I'm not sure about the best way to store all these images. If anyone could kindly share some guidance on this, I would be extremely grateful! Thank you in advance!
