1. read the manual or find one online. it will tell you the minimum distance to use for macro shots. sorry, not trying to be funny just trying to help.
2. use a tripod if you have one or improvise to stabilize the camera
3. depress the shutter button 1/2 of the way down to let the camera focus on the subject. once focused, depress the shutter button the rest of the way down to take the foto
4. use a light above AND below the subject or on each side
5. adjust the white balance to the appropriate lighting. remember that manual, its in there on how to do it
6. if the macro wont focus close enough, switch the camera to manual focus mode and take fotos that way
7. use a plain back grund that is pleasing to the eye. a filthy cluttered tying desk/area is not pleasing
8. go online and get some free foto editing software. photofiltre or photoscape are 2 free ones and are easy to learn and use
9. dont forget to resize you fotos for forum/bulletin board usage. 600 pixels wide will pretty much fill up most brwsers
10. did i mention read the manual
11. 3 megapixel cameras in the right hands will produce fotos as well as 12 megapixel cameras (if my memory is correct, hans weillenman uses or used to use a 3.2 megapixel nikon coolpix 995 camera to take the fotos of the flies on his website and we all kmow how good they look!)
