I have a image gallery, my requirement is to apply diffrent image sizes to all image my html markup is

<div class="post-attacthe-img"> 
<ul>
<li><a><img src="1.png"/></a></li>
<li><a><img src="2.png"/></a></li>
<li><a><img src="3.png"/></a></li>
<li><a><img src="4.png"/></a></li>
<li><a><img src="5.png"/></a></li>
<li><a><img src="6.png"/></a></li>
<li><a><img src="7.png"/></a></li>
<li><a><img src="8.png"/></a></li>
<li><a><img src="9.png"/></a></li>
<li><a><img src="10.png"/></a></li>

</ul>
</div>

Example like: 1 image if its size is 500X500, 2 image is 200X200,
again
3 image is 200X200, 4 image is 500X500
5 image is again 500X 500 and 6 image is 100X100, 7 Image is 100X100
Now again
8 image is 100X100, 9 Image is 100X100, 10 image is 500X500

Şimdi sorun ben ona bir resim boyutlandırma script hangi timbthub.php uygulamak zorunda olduğunu.
