.htaccess makes no images display

[aquarius7373]

• I removed everything in my .htaccess and tried only the code from AI .htaccess, as well as adding it to the bottom and top of my current code. All images disappeared.
• It never made the /ai-cache folder, so I made one for it just in case.
• There are no images in the /ai-cache, and no images load on the site. If I go directly to "http://belleridgeretreat.com/img/logo.png" nothing is there. Empty page. (I don't currently have the .htaccess code in there so my site isn't broken)
• I tried removing all the comments from the code and blank lines, just in case. No effect.
• adaptive-image.php is in my root. I did not modify any file, script or code whatsoever yet.
• I tried loading the page on both safari on mac and chrome on android phone. No images.

I called GoDaddy and they were not able to help me at all. I did, however change "RewriteCond %{REQUEST_URI} !assets" to "RewriteCond %{REQUEST_URI} !img" and all my images showed up. So it seems the mod_rewrite block is working.

What am I missing?!?! Thank you, I need this to work so bad!
