I'm preparing a Google Slides presentation on Ubuntu 20.04, and it involves copying and pasting a lot of png images. Typically I'd like to just open a PNG file with something like Image Viewer, Ctrl+C to copy the image, Ctrl+W to close it, and then in Google Slides Ctrl+V to paste the image.
However, when I do this, about 50% of the time it pastes the image file's path as text, instead of pasting the actual image.
Is there a way to ensure that I consistently copy the image each time (ideally without relying on the mouse)? It's starting to get annoying.
