(This is a general plea to any developers out there inclined to build this idea – I’ve also posted it to the Flickr API forum here.)If you aren’t familiar with it, Tweetie 2 is a state of the art iPhone Twitter client written by Loren Brichter (@atebits on Twitter). I’m a huge fan. It supports a wide range of photo services, like Twitpic and yfrog, but it also allows for use of a custom upload service, documented here: http://developer.atebits.com/tweetie-iphone/custom-image/. I attach photos to my tweets all the time, and I’ve been using twitpic, but Flickr is my home for photos online, and it’s really bugged me to have to put photos in another service, when I’d really just like to keep them all in Flickr. What I’d *love* to see is an API upload endpoint (as documented at http://developer.atebits.com/tweetie-iphone/custom-image/) that would allow users to upload a photo directly from a Twitter client like Tweetie 2 to Flickr, which then returned a flic.kr short URL for the photo (like when you tweet an existing photo from Flickr). If such a thing existed, my online photosharing life would be *vastly* improved, the intertubes would achieve a greater state of harmony, and I’m sure a ton of people would be happier. I realize it’s not a super simple thing to enable (authentication would seem to be the biggest hurdle, but something like OAuth should help), but it would be *awesome*. There are already third party services that are allowing this. http://gdzl.la is one I tested just this morning – it works, but I’d rather have a flic.kr short URL, not theirs, in my tweets. Call it Flickr Pride. And I’d also rather not share my Twitter login with a 3rd party service, which is just bad security practice. So, what do you think? I’m a lousy coder, or I’d try to do this myself. Who wants to score the appreciation and adoration of the people at the intersection of Flickr and Twitter, and build this amazingly great service?
