When creating and adding images to assessments in Schoolnet please note the following:
Insert and image using the icon for images. Do not copy and paste an image from the clipboard. A warning message will alert you if the image is too large. So that images render correctly on a test, they should not exceed 600 x 600 pixels. If you need to resize the image, do so before uploading it. The system supports PNG, GIF, and JPG files up to 8 MB in size.
Additionally you can Access the Equation Editor to insert a math or science equation. You can select one of six equation editors appropriate for different grade levels, with a basic or extended editor.
Remember to add Alternate Text for images.
