Make sure you're submitting only once in each (they have to be validated - so you can't really do that) - and that the pic and herp are both yours. Once the picture has been validated it will show up in the relevant album.
Good luck - hope we see a whole slew of entries this month!
May's winners have been updated on the homepage. Also added links to view the current entries as well as a direct link to submit. You need to be logged in of course but it should make it a little easier.
