pasteing a picture into a cell

Yes, assuming you have the picture on your hard drive, just click on Insert > Picture > From file, then navigate the file path and hilite the file name and click Insert. Regarding the "into a cell" part of your question, if you want the picture to fit into the cell exactly, you can snap the picture perfectly into place by dragging the picture border(s) while simultaneously holding down the Alt key.
