Locating Images

Watch the Visual Literacy by VideobyCredo video below for tips on locating, assessing, and using images.

Image Attribution

There is a difference between citing an image and attribution. Attribution gives credit to the creator of the image.

Below are two examples of how you could give attribution on a PowerPoint slide:


Image Citation

A full citation allows the reader to locate the text or image you've cited. For examples of cited images in different formats, read Cornell University Library's guide to image citation.


When searching the below image resources, use the search tools to find images, that with attribution, are free to use.








  • Wikimedia Commons
    • Wikimedia's files are freely usable, but as with all the images, attribution is still recommended.
    • A site that searches Creative Commons licensed images for use in blogs, presentations, etc.
  • TinEye
    • If you don't know the attribution information for an image, upload it to TinEye. TinEye locates image information.

Image Size

Whether you are using PowerPoint, Prezi or Keynote, an image should fill most of the presentation slide. A PowerPoint slide is 1024 x 768 pixels. The image's resolution will determine the clarity of the image. The higher the resolution, the better. Your image should be 300dpi for tiff and a minimum of 72dpi for jpegs. If an image is blurry in your presentation, it's good to find another, higher resolution image.
