Can I display photos at a different size other than the five in the dropdown menu?

Not at the moment. Tumblr provides the photos at those sizes; the widget just pulls them down from Tumblr and displays them.

More powerful photo resizing is planned for version 2.0. I can't say how soon that'll happen, though.

How can I change the way the Tumblr posts display?

Use CSS. You can add targeted style rules to your style.css file, in your theme folder. Each post is a <li> with the class "tumblr_post." Each post also has the class of its post type: "quote", "link", "conversation", "regular", "photo", "audio", or "video".

Can I import and display someone else's Tumblr?

Yes, you can. But you shouldn't, unless you have their permission.

I have another question that's not covered here.
