It gives an indication of what the quality will be like when you print the
image. For example, the thinest line you can draw in paint is one unit wide
so...
If you have a file that contains an image 100 x 100 and you draw the thinest
line possible, then use a program to scale it and print it out so that it
measures 10" x 10" on the page... then the thinest line will come out at
1/10th of an inch wide.
If you do exactly the same but start with an image 1000 x 1000 print it out
at the same 10" x 10" ... then the thinest line will come out be 1/100th of
an inch wide.
> You also can't change that with Paint, although you can with ImageIt
Changing it after it's drawn can never really improve the quality of the
image. If you start with a line one unit wide line and then increase the
resolution by a factor of 10 the line becomes 10 units wide.
The main reason to change the resolution is to reduce the size of the file -
for example to speed up downloading over the internet - but this also
reduces the quality.
