Making a "New Pics" bulletin is good, but asking for comments does come off as needy.
I like to do it in a fun and humorous way. Post something like, "New Pics! Go check 'em out, you bastards!"
I do that too, like I just recently posted the new pictures to a dance I just went to recently, and my bulletin title was "who still goes to school dances?" and the topic was "I do haha." People will see that I have a new default picture within the dance and will get the message in their heads that I want them to comment my pics.
Anyways, take the best picture you possibly can for yourself. You'll automatically garner comments if you're looking really good. I look really good in the new pictures I posted up and have attracted the attention of a lot of girls. One of my friend's friend said I was even gorgeous.
Pictures that usually go uncommented are the ones that are taken from trips, dinners, outtings, etc. People usually put up a new album with 30 pictures of a trip they just got back from, and most of the pictures usually aren't commented. I know girls who have like 100 comments each picture get 0 comments on their other albums.
