Well, I'm kinda vague on your info, but you need both a vert and horz layout in the same set. A horz layout will not just automatically rotate everything in vert mode.
You can see what is going on if you load a horz layout in the layouteditor and then switch the orientation. What shows in the editor is prolly what youre gettiing in real life: no pics, just blank with the text floating.
What you want to end up with is a layout with <layoutname>V.mll and <layoutname>H.mll in the same folder (or something similar).
