I take the photos on my iPhone, but they're too big to upload here as when I try, I get an error message. So I email them to myself, the iphone offers 4 different image sizes to email them as. I select the lowest size of image (as I've found through trial and error this is the only one which the site accepts) and then upload them via my computer. When I click on the images I've uploaded to make them bigger - I can see all of the details but sorry if they're not the best resolution.
