Sometimes I would like to add an image to the comment. So far, I used postimg, for example here.

To add an image in a question I see that imgur is the default option.

Is imgur the recommended service to add images?

• Who deleted my comment? And why my question keeps getting downvoted? This question has an high rated answer, (thanks @Glorfindel) probably useful for many. My previous comment was "Thanks anonymous downvoter". It was ironic, because after (or before) downvoting is good practice to leave a comment, but the anonymous downvoter didn't do that. Now there are two anonymous downvoters. It's my first question in meta, I'd like to know what I am doing wrong.

• "Thanks" isn't really accepted as a genuine comment, much less so as snark.If you want feedback, ask - don't snipe. Although, an appeal to pre-existing downvoters would likely go unheeded since they aren't likely to revisit the question. Dec 17, 2020 at 22:08

Yes, it is. I usually start writing a new answer, upload the image there, and cut/paste the link to the comment. Stack Exchange has its own 'channel' on imgur (that's why there is .stack. in the URLs), so you can count on that even if imgur somehow would stop hosting images in the future, Stack Exchange will migrate them automatically to a new hosting provider. Also, users in a corporate network where imgur and other image hosters are blocked sometimes have convinced their administrators to make an exception for i.stack.imgur.com since that is vital for Stack Exchange.
