Error with embedded pictures on comment page only

I have narrowed down the problem to having redirects on. It works fine if I turn them off however I want them on for gallery to have pretty links. The error message is this:

Fatal G2 error
Here's the error from G2: Error (ERROR_MISSING_OBJECT) : Parent 16636 path 12

It is only when you click into a page that is not on the front (subdirectory?). My .htaccess looks like this:

# BEGIN Url Rewrite section
# (Automatically generated. Do not edit this section)
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} gallery\_remote2\.php
RewriteCond %{REQUEST_URI} !/main\.php$
RewriteRule . - [L]
RewriteCond %{THE_REQUEST} /v/([^?]+)\.davmount(\?.|\ .)
RewriteCond %{REQUEST_URI} !/main\.php$
RewriteRule . /main.php?g2_view=webdav.DownloadDavMount&g2_path=%1 [QSA,L]
RewriteCond %{THE_REQUEST} /w(/[^?]*)?(\?.|\ .)
RewriteCond %{REQUEST_URI} !/main\.php$
RewriteRule . /main.php?g2_controller=webdav.WebDav&g2_path=%1 [QSA,L]
RewriteCond %{THE_REQUEST} /([^?]+)(\?.|\ .)
RewriteCond %{REQUEST_URI} !/main\.php$
RewriteRule . /main.php?g2_path=%1 [QSA,L]
</IfModule>
# END Url Rewrite section

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Any suggestions on how to resolve this issue?

Thanks,
