Image Hosting Script Help ! Plz

[desicube]

Hi I am running an Image Hosting Script at [a href=\"http://www.imagefilez.com\" target=\"_blank\"]http://www.imagefilez.com[/a]

I am using Php Image Host Script v1.0

I have more than 750 members & 7000 images on my server. Everything is working fine.

The Only thing is that I want to customise my Script so that if give a code for the thumbnail & whenever user clicks on the thumbnail on the forums. He is able to view image on my custom page, which will have header and footer so that I can display google ads on them.

The Output of the Script should be like this... eg xs.to gives the code like this.

[a href=\"http://xs.to/xs.php?h=xs76&d=06151&f=karishma.jpg\" target=\"_blank\"]http://xs.to/xs.php?h=xs76&d=06151&f=karishma.jpg[/a]
& not like this which ImageFilez.com gives

[a href=\"http://imagefilez.com/images/amit/leech1.jpg\" target=\"_blank\"]http://imagefilez.com/images/amit/leech1.jpg[/a]

I am attaching some of the files and database.. plz suggest me what changes should I make or pm me.

The Sql database of Script can be downloaded at
