Wild Card Domains

[wilber]

How can I get images to show on a subdomain that does not exist?

The (I think) easiest way to do this is under "edit zone" in DNS functions in WHM. Choose the relevant zone to edit (they're tied to accounts). Create a CNAME row that looks like this:
* 300 IN CNAME wildcard.domain.com

(* goes in the same column as www, whm, etc. 300 refers to the time to live of the record in seconds; if you don't plan on adding many subdomains, you can increase this number. A client will continue to assume that the CNAME is valid for 300 seconds after it looks it up. A lower number means a greater load on your DNS servers).

Now just create a subdomain wildcard.domain.com and make it a page with the images you want.

Thanks inteluser, looks like you know what you are talking about, I will give that a try and let you know how it goes.
