No. You can add pictures on notes for Mountain Lion though - but I can't get it to sync to iCloud for some reason from there. Maybe it's not enabled yet.
Hey, sorry to bump a really old thread, but does anyone have a solution to this?
I am trying to migrate my stuff out of evernote, and am looking for a better alternative. (too bloated and slow.)
Currently simplenote doesn't support photos, so for anything with a picture in it I was hoping to use notes...and the pics won't sync to the iOS version.
