After browsing the helpful advice in these forums, I was able to get the hotlink protection working. However, it seems the image redirect isn't working.
I found a blog that was hotlinking to one of my images, and when turning on the hotlink protection & reloading the blog, it shows up as a "?" instead of my redirect image.
My htaccess looks like this:
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://art.georgecoghill.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://art.georgecoghill.com$ [NC]
RewriteCond %{HTTP_REFERER} !^http://georgecoghill.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://georgecoghill.com$ [NC]
RewriteCond %{HTTP_REFERER} !^http://design.georgecoghill.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://design.georgecoghill.com$ [NC]
RewriteCond %{HTTP_REFERER} !^http://images.georgecoghill.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://images.georgecoghill.com$ [NC]
RewriteCond %{HTTP_REFERER} !^http://www.georgecoghill.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://www.georgecoghill.com$ [NC]
RewriteRule .*\.(jpg|jpeg|gif|png|bmp)$ http://images.georgecoghill.com/banners/pr...nerd_pirate.jpg [R,NC]
Which is similar to an Apache htaccess help file I saw posted here. The difference is that the Apache file said the image redirect file should end with [R,L] and mine reads [R, NC]. I'm not much of a programmer so I don't know the differences.
Any suggestions?
