Every Cantrip site has a media library sitting behind it: a spot to upload photos, organize them into folders, and pull them into pages, posts, and section content without hunting for the file again. Anyone who's used Dropbox or Google Drive already knows the shape of it. Drag a file in, make a folder, done.
It works like real folders because it is real folders. Behind the scenes your files live in actual cloud storage, organized the same way you'd organize them on your own computer, not some flat list pretending to have structure. Make a "Team Photos" folder and a "Product Shots" folder, and Cantrip keeps that distinction, not just a search box pretending to sort things for you.
The storage limit is real too, and it's tied to your plan. Free accounts get 5MB total across the whole library, 2MB per file, and only the basics: jpg, png, gif. That's enough for a handful of photos, not a full shoot. Paid plans jump to 500MB total and 50MB per file, with more file types allowed. If you're on the free plan and an upload gets rejected, that's almost always why: too big, or the wrong format.
Here's the part nobody tells you until it happens: rename or delete a file in your media library, and Cantrip does not check whether anything else is using it first. No warning, no "this file is in use on 3 pages" heads up. You ask it to delete a file, it deletes the file. If that file was your homepage background, your logo, or an image sitting inside a page section, that reference breaks silently. The page doesn't error out. The image just isn't there anymore.
This isn't a bug, it's just how it works right now, and most people never run into it. Upload a photo, use it once, move on, no problem. It shows up for the handful of people running a bigger library: renaming files to stay organized months after setup, cleaning out old photos, that kind of thing. If that's you, the fix is boring but it works. Before renaming or deleting anything that's been sitting in your library a while, take thirty seconds to think about where you might have used it. Or just don't rename files that are already on a page. Upload the replacement as a new file instead.
Not the most exciting feature to write about, but it's the kind of thing worth knowing before you're staring at a blank spot where your logo used to be, trying to figure out what happened.
