I need to make an effect like this example :
WhatIrealizedbypassingthedebugisthattwoimagesareonedivwithintheother:
<divclass="box-image-differ" style="width: 620px; height: 366px;">
<img src="http://f.i.uol.com.br/folha/ilustrada/images/15203312.jpeg"onload="folha.media.fotoAB.ok( this , '#imagediffer0' )">
<div class="box-image-differ-ui ui-resizable" style="height: 366px; width: 318px;">
<div class="box">
<img src="http://f.i.uol.com.br/folha/ilustrada/images/15203326.jpeg"onload="folha.media.fotoAB.ok( this , '#imagediffer0' )">
</div>
<div class="ui-resizable-handle ui-resizable-e" style="z-index: 90; height: 366px;"></div>
</div>
</div>
But I could not understand how the javascript is done to make the effect, has anyone done something like this?
