To earn hearts you can also go and watch videos or complete missions (just do the purple missions) which gives you a bunch of votes and it's really good.
The other option is to go to the 'photos' section and start rating until you reach 50 images (they give you 50 votes, so that's cool) and that's it.
Anyway, do that every day and you'll get a good number of votes and help our favorites win.
