I inserted a picture in MS Word document but after inserting a picture the cursor is not coming down to the point after the picture so that I can insert another picture or write something. Why?

Have you tried pressing the Ctrl + End keys after you have inserted the picture to force the cursor to the bottom of the picture?

When you insert a picture via Insert|Picture, Word leaves the picture selected. You need to de-select the picture (e.g. by pressing the right-arrow key) before inserting another one. Even then, if you have Word configured to insert the pictures using a wrap format other than 'in-line with text', the cursor won't appear after the picture. For the insertion setting, see:
File |Options|Advanced>Cut, copy, paste>Insert Pictures As.
