Thanks very much. Didn’t realize about the checksum. Interesting. We’ll reach out to you. We are still in the development stage now and the learning curve is high, but we are making progress.
As for your suggestions, yes, this is exactly what we are doing now. But right click and copying, downloading/editing is not really user friendly or scaleable. It would be much easier to click on an upload icon and see existing images, and insert (for admin only). The Topic List Previews plugin does this very well for the topic itself, but not when you want to use other images.
