Posting to TwitPic without ruby-twitpic gem

Hello everyone,

I need to post photos/videos to Twitter. I see that TwitPic seems to be
the most popular way of doing so.

I also see that there is a twitpic gem at github. However, this project
is already loaded with gems and I’d rather not have to add three new
ones (ruby-twitpic requires Nestful and ROAuth) especially since I’m
already using Omniauth, Twitter and Event Machine.

Is anyone posting photos to Twitter (via TwitPic or other) the gems I’m
already using?
