Picture posting is enabled for all :)
Ermmmm so you have to find a photo you have already taken? How does that make sense? Surely we should know what the theme is and then go and try and set up the best photo?
I agree; I'd prefer to know in advance, and then look around, take a piccie and submit. I've just recalled a piccie I sent in as it was not took in March - grrr!!! It would be good to have a month's notice...
