All non-uploaded images are gone

Detailed description of the problem   Forgive me if I sound angry or emotional in any way, I've spent days working on a campaign and now all my work is gone, I'm very frustrated. So, basically what happened is: I was creating some npc sheets using copy-pasted images and everything was fine for some dozen sheets. Suddenly today I was just making another one when I saved and the images were not there anymore. I thought it was odd, so I checked the other sheets and ok, all images were still there, so it looked like an issue with this individual sheet... I reloaded the page and bang, now all other sheets have no images as well. Just like that.   Avatars are still there, mind you. Only the images I pasted as text are gone. Minimum number of steps to reproduce the problem     Paste an image on a description. Save. That's it, it just isn't there, and if you go back to editing mode it will show a corrupted image.

Hi, if I read your post correctly, you've answered your own question. Copy/pasted images in Roll20 will only persist as long as they are in the browser cache. You would need to upload those images to your own library and place them in the various sheets and handouts from there for them to persist across sessions or until the browser ages items out of its cache. If you can upload images from the Chromebook, try that, it should work fine then. If I'm wrong and you have uploaded them, apologies, that would be wrong and a support ticket to Roll20 would be the route to follow. Best of luck, hope it gets resolved.

I have had some luck if the images are posted from an online source, i.e. rightclicking on a browser image, copying and pasting. Copying and pasting from your hard drive nearly always fails. No idea why.

I wonder if there's some magi-parsing going on that uses the URL of the pasted image that doesn't get triggered for local files. My apologies to Ulfberht, I made the situation out to be simpler than it really is.

This is the answer I got from a very smart person: It has to do with the meta data that is supplied by the application that is hosting the copy operation.  When you copy from your finder or explorer, the operating system is storing information about the file you are copying.  When you copy from an application like Word or Chrome, the application stores information about the data in the selection.  When you then paste to Chrome, if the copy was from a selection, it knows the context of how to understand the data.  If it was in the context of a file, it needs to understand how to deal with that information. It's the same way you can copy the text from a text document and paste it fine, but copying the text file on your hard drive won't let you paste that text in chrome (probably) Or how you can copy text from a webpage and sometimes it comes over with fonts and colors and size, and other times with just text, depending on the application that is attempting to read the contents.  All that is meta data passed with the paste operation.

I'm aware I can't just copy it from my computer, I only copied from online sources, like @keithcurtis said. The problem happened despite this. But somehow it already solved itself. The images vanished suddenly, then, the next day, they were back just as suddenly. I never did anything. Didn't understand jack and I'm just praying it doens't happen again lol. But I guess problem solved. Thanks, everyone, sorry to have bothered you all with whatever noobish thing I must have done wrong here.

I blame the agency of an ill-mannered faerie.
