Kompozer version .8a2 is just coming out of the gate as as a well developed beta update to the old 7.10 which was blowing up with newer kernels. I always liked it best of the options on Linux. Closest to the WYSIWYG style editors. Quanta is probably better, but too confusing for me.
I don't do frames, but the drag and drop of images (at least) seems to work.

KompoZer 0.8a2 - Kaz'hack I just exploded the tarball and run kompozer to get it going. So far so good for me.
