How do I get nice themes for Tumblr?

does anyone know a cute simple tumblr theme that shows the display picture, description and has infinite scrolling?

I just recently made a tumblr and i wanted to know if there are any websites that can get some sick free themes or layouts that I can start off with on tumblr. possibly some sites that can add animated effects on some of my photos? thanks

i want to get a rlly awesome theme that you just paste into the HTML BUT!!! it has to be free, and i dont want to download anything to do so also!!! ( and not any of those boring ones that u can choose from automatically off of Tumblr )

Can you guys please name all of the best websites or tumblr sites that have themes. I need a new one. Please and thankyouu<3

i want one that puts pictures beside eachother, in maybe rows of 2 or three, and i want to be able to make my own links n stuff like "me" nd **** thankks, my tumblr is g0lfwang-swag.tumblr.com

hello :) I just made an account couple days ago and I have no idea how to get those cool backgrounds that some ppl have like apparently you click on the person that made it and you'll see themes? but all i see are pictures :( can someone please help...

I want to make a Tumblr so bad but I am not sure how to use it...the only thing that is holding me back is putting up a Theme...if anyone can help me it would be really nice...I have AIM if you want to communicate through there also...Thank you!! : )

I want to really trick out my Tumblr page so does anyone know where I can get some really cool themes? Oh and also some other cool stuff I can add to it?
