Fixed it... I just found out that hot linking was enabled by default on my account and that is was set to high stopping just about everyone from stealing my bandwidth... maybe the Host needs to rethink there default configuration... as when set to high, it isnt a very good idea as it stops the users like me even viewing their own images on their own domain(s)... anyways there support team are now aware of the issue it causes...
The mod_rewrite rules i used to set a subfolder under public_html as my domains main folder was as follows:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^(www\.)?seandelaney\.co\.uk$
RewriteCond %{REQUEST_URI} !^/seandelaney/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /seandelaney/$1
RewriteCond %{HTTP_HOST} ^(www\.)?seandelaney\.co\.uk$
RewriteRule ^(/)?$ seandelaney/ [L]
