To the number of pixels, right click on the image and then click properties.
First I want to thank you for responding to my question of how to tell how many pixels there are. Prior to making this post I tried what you have suggested. I right clicked on the picture and clicked properties and what appears is the following:
Type of file:
Size on disk:
Today I pressed "Summary", at the top of the page, I am not clear what this means. If I am trying to make a poster and enlarge a picture is it the 346 pixels-494pixels that are the factor or the 72dpi by 72dpi that is the factor? I am not familiar with the term dpi. Does the Dpi have to be above a certain number for me to maintain picture quality? And if so what number? 200? 300?
When you see dimensions of an image such 346x494, you multiple those numbers
together and that tells you the number of pixels in the image.
Essentially you are calculating an area... remember the math. Who'dathunkit?
72 dpi refers to dots per inch. Think about making a series of dots... if
you put them close together, they look like a line.
Be careful though, there are terms like ppi, dpi and apply to different
situations. Here is a nice little link that makes understanding these terms
nice and simple. :-)
Last question. Is it possible to increase the dpi on a picture from 72 to 200? When I went to the copy place in Savannah they said that the dpi needs to be at least 200. Almost all of my pictures the dpi is either 72 or 96. Thank you again.
The important thing is how many pixels you have. You need about 200 to the inch in each direction. The PPI value is really unimportant.
Here is a link that may help you resize your pics. It mostly uses photoshop to explain the process but there is a small section at the end to help you in case you do not have Photoshop or Photoshop Elements:
