So should i only adjust the dpi if i need an amazing quality smaller image, or when printing at bigger sizes?

ike,
Actually in theory, it shouldn't look any worse or better than it did before you changed the ppi cause print resolution is dependent on pixel resolution. So as long as your image contains the same amount of pixels, your print will be exactly the same.

Because, when you stretch the image back out to its original size, you are also changing the ppi back to original size. For example...

Original image is 1000x1000 @ 72 ppi = 13.9" x 13.9"

After changing ppi to 200, your image is 1000x1000 @ 200 ppi = 5" x 5"

So when you go to stretch that 200 ppi image back out to its original size, you are basically changing the ppi back out to 72 ppi. By stretching the image, you are basically just reverting your ppi back to 72, therefore your resulting print should be exactly as it would have been if you just left the image alone.
