Course Thumbnail Image Details

When selecting a image for a course thumbnail, ensure to choose an image that is within the Safe Zone (blue highlight) to avoid unwanted clipping of images keeping in mind image thumbnails have additional buttons and details depending on your course status. Make sure that objects or actions can be seen clearly in a 229px x 173px image size.

Using Caution

Images with a lot of text

Limit the words in your image, make sure it is legible in terms of colour, font, and size. Exceptions for abstract images is if the purpose is to showcase a programming language, word documents, and handwriting. For best practice, use the Course Title and Description for text.

Busy or abstract background

With the exceptions, if the topic is regarding about that specific pattern or object (e.g. Aztec, fleur delis, etc...) Some images may be misinterpreted and to reiterate: make sure objects can be seen clearly and actions can be made out easily.

Crop your images appropriately

Unless it is intentional to capture a specific object or action, crop appropriately so as to not lose any important visual data.

Ensure standard image aspect ratio of 4:3

An aspect ratio of 4:3 means that for every four units of width, the picture will be three units high. If images with transparency aren't in a 4:3 aspect ratio, your course thumbnail will stretch.

Protect your content from copyright infringement

Use images that you own, have purchased, credit authors properly, ask permission for image usage or use creative commons license images with caution.

Avoid using animated gifs that loop once and have a vague last frame

If the animated gif loops forever make sure frames are continuous. As for WCAG compatibility animated gifs should stop blinking within 5 seconds. Reference: https://www.w3.org/TR/WCAG20-TECHS/G152.html
