Feature Request: Image clipboard in wiki page editor

Today I opened a wiki for an open source project.

I found image uploading somewhat difficult.

Screen capture & paste to wiki page editor seems to be not supported.

I had to copy&paste in github support page and used the uploaded image link in wiki pages.

Are these links going to be expired?

Image links resemble the following:

Can image clipboard be supported in wiki editors?

Seems like it works everywhere else.
