How much traffic do you get daily? I have a funny pictures site as well - it ranks okay, but the payout is so little I sometimes think it's not worth it. But maybe if you get a lot of traffic and your CTR is good, then it may be earning well?
Intially the key was all submission .I got my ranks to 3 without doing nothing only taking my efforts on submission.Now as google doenst bother much with Dir its time for higher PR links.have couple of high PR and its done.
Some people here are saying they've gotten their PR within a months time, I'd just like to remind everyone or those that don't know. To have done that you have to be lucky enough to have launched your website during a PageRank toolbar update. Those used to come every four months. The most recent one took well over that time period. So don't get discouraged when a few months pass by and you still show a PR0. Whats important is PR is being updated in the background @google constantly so just watch how you improve in the SERP results.
It was still quite easy to get a PR0 -> PR5 in one PR update last year, of course without spending a single $... It should be more and more difficult as time passes...
Usually PR4, sometimes 5 and the occasionaly google authority listing with zero spent on advertising.
seriously, how do you do it. I have been building the sites in my sig and they all have pr 0 and probably won't change for weeks.
PR5 without any money spend. I have actually never bought a link in my life and rank well for around 200 keywords and phrases.
