I'm asking because some people are trying to convince me to upload my photos there…
Is there a way to upload images to instagram while using only free (as in free speech) software which runs locally (not a remote service; except the instagram servers themselves, of course)?
Normally it's easy to upload something; just use the browser and be done, but with Instagram it seems they intentionally made it hard to upload anything except photos made by a mobile phone and via their own proprietary application.
BTW, it's perfectly fine if the application has only a command line interface. In fact I'd prefer this.
A library for a programming language would be good too, it doesn't have to be a full blown application.
So far I only found "gramblr" but it's proprietary.
I'm looking for solutions for any systems, if it doesn't work on my OS, I'll just fix or rewrite it myself.
