How can I make a jpeg smaller?
I have a jpeg that I need to post in Facebook but it is too wide. I want to shrink the size by about 1/3 so that it fits into the space that Facebook allows.
I imported the jpeg into iphoto in the hope of doing it there (I don't have Illustrator or Photoshop) but it doesn't seem to have that capacity. Is there some quick and easy way I can shrink the size by 1/3 so that it fits into the Facebook box?
