It's a marriage, really, between the pic and the text...too much and you lose them..not enough and you lose them.....
It's the building of a fantasy....it's a tease...
I have teaser story sites with no pics that do just fine....and picture stories with text that also do fine...
In the members' area, stories help with retention....
Engines can't help but spider text....
I always recommend text along with graphics....text loads faster...
but you gotta find a balance between the two.
Men do read.
