What kinds of images can I upload for questions?
Several question types allow you to upload images.
Image format: You can upload any GIF, JPG, or PNG image.
File size: If possible, try to reduce the file size before you upload the image. Doing so reduces bandwidth use in the classroom (since all of your students will be downloading that image onto their devices simultaneously).
Display size: Learning Catalytics automatically resizes images that are too large for mobile devices. The image size is reduced to 400 pixels wide while retaining the image's aspect ratio. To upload a larger image, use the Image icon in the enhanced editor. The icon opens the Image Properties where you can enter a URL or a link to an image, and you can manually set the image dimensions.
