Omeka is a digital exhibit tool. You must create items for your images before adding them to your exhibit page. Here are the instructions for doing that:
Can't find an image? Make your own with PowerPoint, Google Slides, or one of these graphic design software options (they have free versions). You can make a chart or graph or pull an interesting quote from a text.
If you need assistance asking permission to use an image, contact Heidi Buchanan hbuchanan@wcu.edu.
Thanks for your care in seeking fair use and creative commons images to post on the site and citing any quoted text.
