Recently at work I had to migrate a physical server to a VMWare-instance. First I made a dump of the live (!!!) system using dd.
dd if=/dev/sda
| ssh [email protected]
‘cat – > /opt/vmware/oldserver/oldhd.dd’
When this was done, I had to create a VMDK-file, otherwise VMWare-server doesn’t understand (there is no support to add ‘raw’ images to an instance. You can create a VMDK-file using dd2vmdk 
After this, I added the virtual-disk to the virtual instance. 
So I powerup the vmware-instance… and guess what… A Kernel Panic occurs 
But… no panic… I started digging into the initial ramdisk. And I found that the SATA-module, which is required for booting a VMWare-SCSI disk, is not available in the initrd 
So, I had two options:
I choose for the second option, the main VMDK-file is a plaintext file and all you have to do is change the entry:
ddb.adapterType = “lsilogic”
into
ddb.adapterType = “ide”
And after powerup the system again… It worked

Recently I found that it is possible to do a referer check within the Apache Webserver, so you don’t need any PHP-voodoo… 
All you need is the next few lines in your httpd.conf file:
SetEnvIfNoCase Referer “^http://www.example.com/” ownsite
<Directory “/usr/sites/www.example.com/pics”>
Order deny,allow
Allow from env=ownsite
Deny from all
</Directory>
So other sites will receive a 403 forbidden message from you webserver if they try to link to a file in your pics map
