well, sort of... if the photo of the "beautiful" person was actually using your product or services and getting a really great benefit from it (i.e. a super big smile, etc) then the phrase "a picture paints a thousand words" would come true.
unfortunately most web designers just use stock photography and don`t really care, and the website owners don`t hold the candle to them to care either, because either they have no knowledge of why they should make the extra effort, and secondly they don`t want to spend the money top get it right. i think the effort to get it right would return so much more profit, then the half effort to just get it done. but trying to get the camera to capture that moment takes skill and skill costs money.
if anyone has seen photos like this, please post some links here so we can get the understanding of how well it works. i`m wondering if a large company like Verizon "gets" it. But alas, I just went to their website (http://www22.verizon.com/) and there is the token beautiful model, staring blankly into space. You can`t tell if she is using a phone, or using the internet, or has just taken some extasy and is higher than my cell phone bill. Does this work to drive conversions? or is the cell phone so popular that it sells itself, and we wouldn`t care if you put a photo of a gorilla holding a banana to it`s ear, it would still convert to sales?
