Drupal 7.x

Is there a way output the relative time stamp an article was posted, e.g. 1 hour ago, 2 day ago, etc?

I just discovered Drupal 7 last Friday. I've been fairly successful in stumbling through it, and even better after reading the Beginning Drupal 7 book.

Can someone delete this?

what would be the best way to go about adding the following functionality to my website.

Then I want to be able to keep a record of all the scores assigned to each image (so that I can report back how many times an image was scored high, medium or low).

are there modules that would work great for this?
