Javascript Random Images - 8/25/2005 0:38:55
Hello, I was wondering if using Javascript for random images would effect accessibility at all? Basically all I want to do is swap images on page load (the images are only for 'pretty' and not for content).
Have read through Creating Accessible JavaScript and think it will be okay if I use alt="", but am not 100% sure.
Have found some articles on doing this without Javascript, but they all use server side scripting and I'd rather keep this as html.
Thanks for any advice 
Sally

Hi Sally
As long as it's "just for pretty" stuff I'd say you're ok. I'd use the alt="" for images that that are structural for instance lines or bullets or for something that would generally be more confusing and annoying than enlightening for someone using a text reader.
I tend to include structural images in the CSS and they don't have any sort of Alt tag so I guess you're effectively doing the same thing. I've no idea what Alt="" will do to your validation if you do that though!

What exactly is it falling down on because I've got this sort of thing to work in the past at xhtml 1.0 strict?
I find that commenting the script out like this helps too (sorry if you're already doing it!):
<script type="text/javascript">
//<![CDATA[
document.write('blah blah')
//]]>
</script>
Or if it's still causing you problems then can you remove the script itself to an external .js file?

Hi, you should be able to include your text along with the image path and link like:
image[1]= "<a href=\"http://www.computerhope.com/history/newslet.htm\"> <img src=\"http://www.computerhope.com/banners/banner5.gif\" alt=\"Computer Hope Newsletter\"></a> <p>Here is some text.</p>";
Is that what you are after?

Back to the drawing board I guess.
