Yeah, nothing easy, at least.
You could do the following, but it would be a
huge PITA.
- Take the picture
- Upload it to photobucket or the like using the appropriate
App Store app
- Navigate to the picture in Photobucket in Safari
- Use the
iCopy bookmarklet to copy and paste from the Photobucket page to Macrumors.
This is really actually pretty much the one and only thing I want copy/paste for. I am mostly content with mobile Safari except for the lack of a mechanism to forum post pictures...
I think that's such a nuisance that I wouldn't bother doing it. I think what a lot of people are doing if they want to make photos available is to put them in a special sub-album in Photobucket, Flickr, or whatever, and then leave the link to that album in their signature. I know one of our members who was on a world trip was doing this with his photos taken in various exotic and not-so-exotic (including Chicago

) places.
