server questions?

im trying to get organized. my question is if i have 1 host w/ my main domain and then i have several add on domains running different forums. is it ok to have 1 folder in my root that holds all my images for all the skins i use on all my sites? my thinking was it would keep me better organized and i was also curious to see if it helped speed that my skin images folder wasnt 3 or 4 folders deep from the root. does cookies or anything else like that hurt me if i did it this way? i use complete paths on most my skins cuz of add ons anyways?

thanks in advance

its not going to hurt anything to have all of your images in one place
