Image resizing 1

[webmigit]

I have a server side scripting generated catalog and I need to do a little image manipulation..

I know that cold fusion has third party tags available but I'd like for the server not to do the work, what I'm wondering is...

Is there a way I can say like...

<img src=&quot;image.gif&quot; onLoad=&quot;checksz(some_sort_of_identifer);&quot;>

and function checksz would be like..

function checksz(imj) {
if image.width greater than 75 {
image.width = 75
}
}

<img src=&quot;image.gif&quot; onLoad=&quot;checksz('myImg');&quot; id=&quot;myImg&quot;>

function checksz(imj) {
theImg = document.getElementById(imj)
if (theImg.width > 75) {
theImg.width = 75
}
}

Great, that works great..

But I ran into a problem, if you back into the page you get big images, because.. the images aren't 'loading'... Anyway around this? When you back into the page, it still resizes?

Unfortunately, when users use the &quot;back&quot; button, no javascript events occur on the reloaded page, which will make that difficult...

What about adding a 'no-cache' statement to your meta tags at the top of the page?

I forget the exact context of its usage, but I'd think that would cause your pages to always auto-reload.
