DVD Download Sites / Screengrab Content

So im about to start working on another affiliate program, this time dealing with DVD download sites, where a surfer pays a membership fee to access a site in a specific niche filled with hundreds of DVD titles, split in to full scenes along with entire DVDs.

My question however is this...

Do you think it would be worthwhile also including screengrabs of the DVDs to use as 'image content' inside these sites members areas also?

Personally, im not a big fan of seeing screengrabs inside a members area being used a pics but im wondering if it would be somewhat expected by a surfer/member hitting a site of this type?

Your thoughts, do you think screengrabs would be good to have inside such a site if promoted as 'image content'?

Regards,
