How to post photos to instagram from a computer?

I recently, well… Dropped my Iphone in the ocean… So I can't get an update for a while and was wondering if there was anyway that I could post pictures to instagram using my mac? I have already been using statigram for an instagram viewer but I would really like to post some photos. Any ideas?

No. Time to buy a mobile phone.

That's what i'm trying to figire out
