I'm going to go out on a limb here with pure speculation - I've seen many sites rating very well in the current SERPS with slide shows above the fold. I am working on the assumption that this type of content is fine. This type of content would not be adsence of any type of advertisements. This type of content also keeps people on the page for a longer period of time.
On the other hand I am not putting all my eggs in one basket. I'll be OK if Google says no to these pages.
