Happily it's not too tricky to get the 'perfect' submission on LitterLotto.
In order for a submission to meet our entry criteria a picture must have/ be the following;
1) A picture of either a hand or a litter grabber/ picker holding the item/ piece of litter
2) The item should be positioned just about the lip/ entry point of a bin (or bin bag in the case of a bulk litter pick).
3) The image should clearly show the item (the valid items considered as litter are explained in detail in our T's & C's).
4) That's it!
