Promotional material - Wallpapers & Utilising social networks

We created some images using photoshop which we will offer as freebies to our twitter and facebook followers. This in essence should gain us more viewers & gain a fan base for the characters involved. Many distribution companies utilise this technique to spread word about the film and gain a loyal following. Social networking will allow us to distribute these for free and allow people to "retweet" or "share" these with their friends on social networking sites.  One features our tagline , "It's all in the mind" and another features the Film name . We added just the tagline to one so people can build an association between the two.
The images were created in a widescreen format , enabling compatibility with the latest desktops. As these images are huge (1599x913) they can be scaled down to suit smaller screens as well.
When deciding to upload these to twitter , we "tweeted" this first "Follow us for the latest info/news & updates. Releasing a poster exclusive to twitter with the next 10 followers" This is a technique used by many musicians / actors / film & movie companies to ensure more followers in exchange for exclusive content. People will tell their friends to follow so the required number is met, and in return they gain the content which they can't get anywhere else, in this case a poster. The second poster is going to be released in a similar way on facebook, however with 10 page likes.
