Using the new CSS attributes of IE5.5 or above, use JS to determine if the image size is larger than a fixed value, use ZOOM to zoom.
Create a behavior file named zoom.htc, the code is as follows:
<public:attach event="oncontentready"" onevent="zoom()" />
<script language="javascript">
function zoom(){
if(this.width>760)this.style.zoom=1/(width/760); //ZOOM=1 divided by (width divided by the specified width)
}
</script>
Specific application of this behavior
Add the following code to the web page:
<style>
.hyperlook img { behavior:url('zoom.htc')} //Note the path of ZOOM.htc
</style>
Finally, add in front and after the places you need to control: <div class="hyperlook"> </div>
The above is just the solution in ie
