Android: How to copy an image for copy/paste?

[JEDI]

One forum I Belong to allows you to just paste the image instead of uploading.

Copy/paste puts a big pic in my post.
Uploading the pic puts a small avatar size pic and people have to click on it to enlarge.

But I can't figure out how to copy an image in Android 8.

Thx

Android 8? Kinda' old.

I'm on Android 11 on one device and I can tap/press and hold. A dialog box comes up with options.
