A) right clicking am image and pressing copy image url ( in chrome ) copy image adress ( in safari ) gives you a direct link and i suspect the option will be in i.e and firefox
i agree
C) as i pointed out in a its simple
D) yes and no, if you compare the links in what i posted erlier the direct link loads 10x faster then the photobucket link, this may vary depeding on internet speeds etc and hosts, ( dev and photobucket are slow image shack isnt so bad ) the only major difference it makes is my willingness to see someones artwork they've taken time to create.
anyway ill stop posting here now time for bed
anyway final thoughts : its a good idea but itd be better suited as a ?moral? rule insted of set in stone as such, what i mean is that it wont mean your images get taken down but you may be asked to give direct links but you dont have to at your own choice, the only problem i forsee if the rule was setup that way is what welsh said about "mini-mods"
