[Feature Request] Resize image to % of the original

[tomas-chrastina]

I would like to have an option to resize image of any size (even small one) to 50% of the original.

This could be helpful scenario with custom display scaling. In my configuration images are crazy big after pasting to an email. Therefore I need to reduce size most of the time to 50%. Now I need to calculate and change size manually all the time.
And it is not the most practical.

So to have an option to resize any image to specific ratio/percents of the original size would be much appreciated.

Maybe there is another way how to achieve it. But I did not find it.

Thank you in advance.
