Other than the site you’re on now, here are a few of the other sites that I put together and maintain:
I put together a simple site for The Military Ration Museum where I could showcase a cross-section of the collection, display a few examples of the rations I've been 3D-Modeling, and give folks a way to reach out.
For the museum collection, I wanted a site that was open source, easily updated for myself and volunteers, and FAST. I used Collection Builder so I could pretty much generate the site from a spreadsheet. In the background I put together a few extra scripts to slim down and watermark the images.
