Until recently Twitter users who wished to share multimedia content such as photos or video were forced to use a third party API. Recently, however, Twitter has developed it's own photo/video sharing tool and opened it up to all Twitter users. Users may now notice the Twitter interface looks a little different. When a logged in user clicks into the Twitter text box to create a tweet they will notice a small camera icon that appears beneath the text box's bottom left corner. 

Clicking this icon will prompt the user to select an image they would like to tweet to their followers. Once a photo has been uploaded tweets containing an image will contain both a thumbnail image and a link to pic.twitter.com, which is powered by PhotoBucket. The tweeted image must be in jpg format. The tool does not recognize bitmap (bmp) files.  The biggest limitation to using the Twitter photo/video sharing tool is that it lacks the immediacy of other photo sharing resources. The interface limits the user to tweeting photos saved on their PC so it is not very useful for sharing photos on the scene or captured via smartphone.

Here is a sample tweet that I did using the tool.

For reasons unknown the tweeted image resulted appeared with distorted color.  

Pros: 

Easy to use. 

No longer need a third party tool.

Cons:

No ability to share photos taken via smartphone.

Random color distortion of images.

Glitchy, slows down the Twitter API.
