is there a way to make instead of an src image (the quickly loading image that comes before a larger image to show what is coming) a bar maybe 100px wide and 15 px tall in the middle of the image space using javascript? and using an image you provide, like a 1x11 tall fill, the javascript puts like one for each percent of the image loaded so far? do you get me? sort of like what some flash files do. it would also be good to have a % number there. is this all possible?

is it also possible so that instead of 1 per 1%, you could just have like 5, so the javascript automatically puts 1 for every 20%?

help is appreciated
