HOWTO: get a highest-resolution version of an image on Last.fm

Sometimes you can find an interesting picture on Last.fm, but don't have an obvious option to zoom in. Fortunately, sometimes you can view it in a better quality too (it depends on the originally uploaded image resolution):

1. First of all, copy the URL of a necessary image; you should get something like this:

   http://userserve-ak.last.fm/serve/64s/35346791/RJ+Test+Artist+1+knifefighttypepadcom.jpg

2. Then you'll need to modify the URL a little; just replace the entire substring consisting of alphanumeric characters between the two slashes after the "serve" word and before the image number with a single underscore:

   http://userserve-ak.last.fm/serve/_/35346791/RJ+Test+Artist+1+knifefighttypepadcom.jpg

3. Just paste the modified image URL into your browser's address bar and enjoy the (big) picture!
