I have taken a lot of photos on a FinePix S9600 9 megapixel camera and want to create a collage of 220 of them. The photos have attributes 3488x2616x26b jpegs.
When I copy photos into publisher to create the collage the image is sized as if it will be printed at 72dpi (I think) with these measurement dimensions.
I presume I will really want the photos in at about 1200 dpi for when I print them so they dont look grainy.
How do I change the attributes so the photo is at 1200 dpi instead of 72 so when I drag the photos onto my sheet it is the correct size?
