For the unfamiliar: Anytime you are getting belayed with a rope, you are not bouldering. All but the very top picture are considered "top-roping". Bouldering problems are much shorter (generally under 20ft) and require you to exert a shorter, but greater amount of effort when compared to roped-climbs of a similar grade of difficulty. It's similar to comparing a sprint and marathon.
