I find there is little difference if I take a photo with my phone or with my camera... I still have to transfer it to my computer and then upload it. Thus the fact that someone uses a phone is really not justification not to follow the requirements that are set by category.
In fact depending on the browser used on the phone a person can upload to the site directly from their phone.
Thanks for your thoughts, Bruce S. As far as I know my phone is not capable of a direct upload to my computer ... in my phone I have to click to "share" the photo elsewhere (for the sake of example, let's say Google+), then go to my computer, pull up the photo at Google+ and save the photo from there to my computer desktop, then upload to Waymarking.com. A lot probably depends on the type of phone each person owns, however, because it sounds like yours can do a direct upload. Definitely something to look for in my next phone!
