#<term>: This adds a hashtag in order to tag a tweet with a search term. The hashtag is usually placed at the beginning of the tweet.

Twitpic.com and instagram.com: There’s no way to attach a photo to your tweets as you would to an email. However, there are a number of third-party platforms to help you to upload and share photos easily. Twitpic.com is one of the most popular sites for this, or you can simply share a shortened link to wherever the photo lives online if it has a URL. Instagram.com is quickly becoming the tool of choice. The great thing about Instagram is that you can choose to have the option “View Photo” appear under your tweet; then, when somone clicks on this, they can see the photo.
Hootsuite is a great third-party platform that has been created to make it easier for you to manage the conversations going on within your Twitter network.
