There are tons of websites that allow you to host your pictures. Unfortunately, the links to those files are almost always too long for Twitter.
The Twittimg application makes tweeting and managing your picture files easy as pie.
Every Twitter user, already has a Twittimg account waiting for them. To access the account, all you have to do is log-in with your Twitter username and password.
Twttimg allows its users to upload picture files in the jpg, gif, jpeg and png formats only. TIFF files and bitmap files can’t be uploaded to the servers.
Each picture must fall within the 2MB limit. Pictures over 2MB will not upload.
Keeping track of the pictures you’ve already uploaded is done by clicking on the ‘My Photos’ section. Under that section, you can see all the pictures you have on the site, as well as their statistics.
All pictures can be viewed by the public. There is no option to make your pictures private. As soon as you upload a picture, it is automatically posted to your Twitter account as a status update. Each picture is also given a designated link so you can share your photographs with others.
Twittimg also allows you to create a caption for your pictures before you upload them. However, in this instance, you can only write up to 140 characters.
