What I try to get with "!htbp" written in the header is a float position closest to the position I have it within the Lyx-GUI. Everthing works fine, except then the float doesn�t fit to the actual page and the "p"-option takes place.
I suppose that your image in the float is wider than the
textwidth/textheight. In this case LaTeX overwrites all placing parameters and chooses p, which is a float page _without_ text.
try to decrease your image size to 50% of textwidth. If then all works well, choose a width of 100% of the columnwidth
