We have students who are using Theia that instinctively click the image files in the navigator expecting them to open as a preview, however they are met with a dialog that says:
The file is either binary or uses an unsupported text encoding. Opening it might take some time and might make the IDE unresponsive. Do you want to open 'assets/bomb.png' anyway?
This can be fairly confusing, as one would intuitively expect that the image would “just open”.
Is there a way to have the image open as a preview instead of the text editor?
