Find your post, whether directly from your page or your tumblelog, then at the right corner you'll see Edit Delete and Dashboard buttons, click delete, ok and that's it.

According to tumblr, "If you want to incorporate your tumblelog on another web page, you can use the following code to embed your posts as basic HTML that you can skin with CSS."

Basically your tumblelog code will look something like this

<script type="text/javascript" src="http://designedbyjackie.tumblr.com/js"></script>

You can find your specific code by logging in to your tumblr account, navigate to goodies, then middle right hand column, select the heading that says "embed your blog" Copy and paste that code in the div that you would like it to show up.. Voila

You can take it farther with some CSS magic

Tumblr is a free blog hosting platform that allows users to post text, images, videos, links, quotes and audio to their tumblelog. Users are also able to reblog other posts not created by them to their blog.

To change your display picture on tumblr you need to go to your tumblelog (not your blog) and click on settings. You'll see the picture that you already have and a "Browse" button. If you click it it'll give you the option to choose a picture from your computer that you want to use as a new display picture. Then you go to the bottom and click on "save preferences" and that's it.

Tumblr is a microblogging website, meaning that users typically share small bits of media or information like sentences, pictures, or short videos. Tumblr is also generally considered to be a social networking site in the sense that it allows people with similar interests, backgrounds, or hobbies to connect and develop virtual communities.

On Tumblr, users "follow" other users, receiving their microblog posts on their dashboard. One key difference between Tumblr and other social networking sites like Facebook and Twitter is that Tumblr places substantially less emphasis on real-life connections and encourages a more private form of social networking. While Facebook communities are based around "friends" who often know each other in real life or have some form of real life connection, Tumblr users often follow people who they have no other connections with other than a shared interest or other similarity discovered through Tumblr.

Of course, some Tumblr users do use their real names and pictures and do interact with people they know in real life as on Facebook. The key difference, however, is in the design of the website - Facebook emphasizing transparency in knowing who you are friends with and Tumblr emphasizing levels of privacy and anonymity (as can be seen with anonymous asking and other features).
