Great! To place an image on the community, do you mean the background image? If so, there's a place in the "edit commumity" forn on nostrudel for that. If you just mean an image in a post/note, just add it the way you would add an image any other time ( I think). At times I've found I need to host the image somewhere, anywhere, then copy paste I. The url to that image.

I am speaking of banner image/ profile image. The one thing I saw was URL. I did not see any other way. Plus I am not sure of the meaning in your reply of this phrase "forn on nostrudel" when discussing "edit community"
Sorry, typo. Should have been "form" on when trying to edit a community. That's the only place and manner I saw as well. Maybe this is the type of thing that will grow out a nostr does.
Is there a better source? My images from https://nostr.build/ look cheap and distorted. Most other community pics look crisp and clean?
You can use any source you want as far as I know for hosting images. Maybe upload to nostr as if you were going to include the image in a note, then copy/paste the URL into the banner slot on the form. I do a fair amount of stuff on the Hive blockchain, so I have several images housed there (hive.blog or peakd.com) and just use the URL that points to those servers. Maybe this helps.
