Resizing Images In Photoshop 6
Open the image you want to resize
Adjust the image's size by going up to Image>Image
Check the image resolution.
Be sure your Resolution
is set to 72 if you're outputting your image for the web. Your image
will be much too large for the web if it's set to anything higher.
If your Resolution was set to
something higher than 72, you will notice that the image will automatically
be resized once you change the Resolution
to 72 if Resample Image is selected.
To adjust the Resolution
of your image without affecting the image size, uncheck the Resample
refers to how many dots per inch (DPI)
or pixels per inch (PPI). Web Resolutions are always set
to 72 since that is the maximum your computer monitor can display.
Print values for Resolution range
from 150 and greater.
Another reason not to use higher Resolutions
than 72 for the web is file size. An image with a Resolution
set to say 300 has about 4 times as much information in it. This
is important for print media because of the level of detail needed
to produce an acceptable print, however, that same image would be
much too large of a download for someone to wait for. And since
the majority of people on the Internet are using 56k modems, you
need to design your images for that audience.
When the Image Size dialog box opens,
you can input the new sizes you want for your image. Be sure to
have Constrain Proportions selected.
This will ensure the ratio of height to width
are maintained and will prevent your image from being distorted
or unevenly resized.
