Yes, onLoad dosnt work normally in IE, you have to set a timer and look for an image resize.
This technique doesn't really help when trying to move between different frames of a icon animation, however. (as they are naturally all the same size). Also, I'm not sure that onLoad would really trigger when the image updates on the screen, rather then just being loaded. In my case all the images are likely loaded and in the cache already. Its simply a case of URL's being changed but the image in the Dom on screen not being for a set time (X) after...despite it being previously loaded. In order to make an animation that is actually visible for the end viewer, I seem to have to either know that X value, or need a method of detecting when the image has visible changed. So far the only idea I have is to have all the images marginally different sizes, by adding 99% transparent pixels to the edge. Then looking for the change in the Dom. This is, of course, incredibly crude, a lot of work, and only usefull for absolutely positioned elements. Its also, of course, worth pointing out that animateing between image bundle frames is a lot more effective and seems to update every time. But sometimes you need user-determained stuff loaded at runtime. (in my case, Im constructing a game-engine run by script files) ~~~~~~ Reviews of anything, by anyone; www.rateoholic.co.uk Please try out my new site and give feedback :) 2009/7/27 Sean <[email protected]>: > > This kind of thing, with images has always been tricky for me as well. > Images seem to be a beast all onto themselves, and seem to be severely > different depending on IE to FF.
