I think its because your running timthumb script in wordpress and its not configured correctly? Let me know!
Is this site an add-on site on a shared hosting system? I had this problem yesterday when I set up an add on domain on hostgator. If you set up hotlink protection on your main site and add on a domain, you have to disable the hotlink protection on your main site. If this this is your problem, let me know.
I am running timthumb, but I dont know how to configure it properly.. also I'm running the website on freehosting.com, could this be the problem with hotlinking? could really use some help :/
I don't know anything about timthumb or freehosting.com. Use the KISS principle. If you don't know how to configure a plugin, get rid of it. Deactivate and delete the plugin. Wordpress doesn't need a plugin to manage images, SEO, robots or other basic stuff.
