.... but am in two minds as not sure whether there will be some viruses with this one.  Guess if they submit it to Imgur it should be OK?

No one can tell. But Imgur already protect themselves by stating that "all third party tools are not affiliated by, or supported by Imgur".

As a general rule, you should always scan for virus before you run any Windows executables on your desktop.

And the one you choose is open-sourced. You might inspect the source code if you want. https://github.com/bkeiren/EasyImgur

You could even create a new dummy Imgur account just for testing the tools you worry about.
