Last week Twitter released a new feature allowing ou to upload images to your tweets easily.
You can upload any image that’s up to 3MB in size. It will then appear as a link in your timeline and when the tweet is clicked it displays the image in the details pane.
The images themselves will be uploaded to twitter.com but they will be hosted on photobucket.
Don’t worry if you want to use services like Flickr, Twitpic or yFrog they’re still supported by Twitter.
For more information about this new feature check out Twitter’s Documentation on Image Uploads.
