htaccess rewrite rule for loading image from another domain

I am developing a multidomian admin panel in laravel. We upload images for specific domain inside admin panel example.com image: http://ift.tt/2ehLHqu

now inside domainname.com i want to use

<img src="http://ift.tt/2eQWEvE" >    

instead of

<img src="http://ift.tt/2ehLHqu" >

approach i am using for this is i have a controller responsible for getting image content

http://ift.tt/2ehGmj3

and then i am using htaccess

AliasMatch "^/uploads/$"   "/home/dir/public_html/example/public/uploads/$1"

RewriteRule ^uploads/(.*)$ image?path=uploads/domainname/$1

but it's not working. Any help will be greatly appreciated. Thanks
