Will do on the breadcrumbs (link tree as you call it), I use this on my own site, but it's not a native function so I didn't think about readding it in.

For the reply, check what Diocletian said, the editor being defaulted is considered "basic" and you probably aren't seeing all of the functionality actually available. (Click Settings, General Settings on the left).

I'll increase the size of the images a bit, once I do , you'll have to reupload your image again as they get resized (which is why it worked when you uploaded it, but not linked to it). I'll post here again when I make that change (at work right now, will do it when I get home).
