Thank you for your quick reply. I forgot to add that I plan to use your template to upgrade my old blog with 1000+ posts with images sourced externally via link. They are not featured nor embedded into WP database.
I did try to build my theme in Genesis with Dynamic Web Site builder before I found about Iconic One Pro and scaling of theme was OK.

Could this (external images) be a problem?
