figureandtableenvironments inbeamer. These are floating objects. You should just use\includegraphics{...}for images and\begin{tabular}... \end{tabular}for tables. See Figure in Beamer, General question on floating and non-floating objects in LaTeX and Label and caption without float for some discussion. (And forbeameryou probably shouldn't use captions anyway.) – Alan Munn Nov 17 '13 at 05:11beameris not very awful. The problem is that there are various things that you don't yet understand about LaTeX, and so you are making many (common) beginner's mistakes. – Alan Munn Nov 17 '13 at 05:26figureis a floating environment, you are still a beginner, even if you've been using LaTeX for ten years. Sorry. Yes,beamertakes some getting used to, but there is an excellent tutorial in the manual, and it really is quite powerful. If you have any math at all in your presentation you surely can't be serious that Powerpoint is a better option. – Alan Munn Nov 17 '13 at 05:33\captionsetup[subfigure]{labelformat=empty}.You needcaptionpackage to do this. If you don't want the caption too then simply don't write into\subcaptionbox{none here}. Sorry the system thinks we are chatting so I put my answer here. – Jesse Nov 17 '13 at 08:45
