images appearing blurry

Found out what the problem was…

When adding the new slide to the slideshow from the Media Library, you have the option to “Show” the details of the image. Click on that, and make sure the size you are inserting the image into the slider, is the size you want. My problem was that I knew my original image was 800px wide, and that it was showing blurry. This was because I was inserting the image as “Medium” sized and didn’t realize it. When I switched to “Full” size, it looked correct.

Hope this helps someone else!
