take a look at onkeypress

Edited by |-|x because: typo
Member Avatar for xDancinPoptartx

so I got

var whichPicture = Math.round(Math.random()*(p-1));
onkeypress =
function showPicture(){
document.write('<img src="'+thePictures[whichPicture]+'"align = right >');
}

which that does a key press how to i set it to the left arrow or right?

I think this is what you are trying to accomplish:

Just so you know, random numbers in javascript aren't that random, so there is a method in there that gives actual random numbers (for the most part).

Also, don't use onkeypress as it won't pick up the arrow keys, however onkeydown will (and more than likely onkeyup).

oh, and for what you want, you'll want to change the numberOfImages variable to 150, hope this helps.
