Question

how is inserting a shape different from inserting a picture

Answer 1

The steps involved in inserting a pic are different from those of inserting a shape.for e.g:
To insert a shape,just select the shape u want to insert from the status bar or home menu.
To insert a pic,select the option:insert picture and choose from which file u want to insert it.

Inserting a picture is probably a bit more longer process than inserting a shape and u can select the pic from any saved file but u can only insert a shape which is present on the menu.
