Check the permissions on the images folder, is it 755?
Also, how did you create that folder? via cPanel, FTP client, etc?
Here's what's weird about that "images" folder. Because you don't have "indexing" set to "off", normally when you access the URL like:
http://www.mrmstudios.com/images/it should say
"Index of /images", instead it says
"Directory of /images/". Now, the word "Directory" is what's unusual, cuz it should say "Index".
So, there must be something in some configuration somewhere that is treating that "images" folder differently than any other folder. Even the "public_html" would say "Index of " and not the word "Directory of ".
Maybe somebody can figure out why that is. I tried different setting to see if I get a folder on my server that will bring up the words "Directory of", but nothing I do does (I only get "Index of" - as it should be), so I can't figure it out

What do you have in your .htaccess file? Maybe something in there is causing this phenomena

Do you think you might have entered the word "images" in anything on cPanel (parked domains, apache handlers, etc.) by accident?
