Restrict Posted Image Size [CB]

[california]

Tired of n00bs posting huge images that stretch out the width of the board? Worry no more This code will automatically resize all posted/sig images that have dimensions greater than either of the ones you specify, but keep their proportions correct.

<script type="text/javascript">
<!--
/* set max posted image size with click to enlarge by california */

var maxWidth=500;
var maxHeight=300;

var img=document.getElementsByTagName("img");
for(i=0;i<img.length;i++){
    if(img.alt.match(/\[image\]/i)){
        img.onload=function(){
            if(this.width>maxWidth){
                this.style.height=""+(this.height*maxWidth/this.width)+"px";
                this.style.width=""+maxWidth+"px";
                this.style.cursor="pointer";
                this.onclick=function(){
                    window.open(this.src,'imgwin','');
                }
            }
            if(this.height>maxHeight){
                this.style.width=""+(this.width*maxHeight/this.height)+"px";
                this.style.height=""+maxHeight+"px";
                this.onclick=function(){
                    window.open(this.src,'imgwin','');
                }
            }
        }
    }
}
// -->
</script>

Update 13 July '05: Code now resizes all images after they are done loading, so no images should be skipped and they shouldn't need to be cached anymore.

Update 29 July '05: Added back the click to enlarge feature.
