No other images can be shown?

First of all, thank you for the fantastic tool.
I have tried it with my images stored on, e.g., a Google storage server. However, the demo site and a local version both only show the example tissue (skin with melanocytic lesion). In your code, there this address is the default address?

One reason I can think of for that could be because the images on the Google storage server are not publicly accessible. The tool works from your computer, so it can only see data that your browser can directly. And there is no authentication/authorization built into the app, so any images requiring special login are not directly supported. Not to say that that's not possible, it's just extra functionality that is not part of the demo itself.

Just to verify if public accessibility is the reason, can you try opening the image URL in a new browser tab directly? Are you able to download the file when you do that, or does it give you an error?

If the image is downloadable but the tool still cannot open it, a CORS configuration might have to be added to the storage bucket to support browser-based access. More info on that here: https://cloud.google.com/storage/docs/using-cors . Apologies for the trouble, this is unfortunately a security measure browsers employ that the tool cannot circumvent.
