I glanced at some of your hubs and it looks like they are all single text blocks. Do you realize you can add as many capsules as you want?
Each paragraph for instance can be a single text capsule so that image capsules can be placed in between them. Your other option is to have an image lined up with the top of a text capsule but aligned right so the text flows around it.
Lots of times I build my hubs where every paragraph is a separate text capsule even if I don't plan on putting an image in there. I have a couple hubs that probably have 30 capsules in them. There is no limit that I know of.
I use a lot of images in my hubs if you want to look at them it should give you an idea of what is possible.
