That’s a question that I for which I was not able to find the answer on Google.
So much for being able to find everything and anything on the Internet.
For those of you who use stock photos or your own images in your line of work, I got the following information from tech support at www.istockphoto.com, which is a very low-cost source of stock images. (Yes, Getty Images, in general, is higher quality, but so is the price.)
For PowerPoint presentations being displayed on a computer screen:
Use 72 dpi images (istockphoto “small” image files)
For screen projection presentations:
Use 300 dpi “medium” files.
The “xsmall” files can be useful for:
- Web pages
- Selected PowerPoint presentations (if the image fills only a small part of the slide and/or you are using a low screen display resolution)
