Because of the funding the University receives, we are bound by federal law on accessibility to make sure everyone is able to experience the content on our site. A recent legal agreement between the University and the Office of Civil Rights in Washington, D.C. also obligates us to make our site content accessible. Plus, Extension’s purpose is to help people, including people who have an ability difference.
Alternate text, also known as alt. text, helps people with visual impairments who use screen readers; however, not everyone with a visual impairment uses a screen reader. So, adding alt. text to an image with text on it will still leave some people with disabilities unable to experience the content on our site.
The accessibility checker that is used to monitor the University’s compliance with the legal agreement has a manual check in place that causes every single image to be examined for text. If an image without text cannot be found, the University’s placeholder image for missing visuals will automatically show up.
Tip: Check out LinkedIn Learning for videos on how to prepare images for the web.
There are three preset image types for an Extension program: content blocks, banners and thumbnails. These image types show up with program mentions throughout the website. Each program can have only one of each of these image types.
Content blocks are required for Extension programs. These images show up on the All Programs page, in the Featured Programs ribbon and as related programs within website areas and in the sidebar on publication webpages.
Content blocks must be:
• 800x600px (4:3 ratio)
• Less than 200kb
Banners are the long, skinny images that show up behind the program name on Extension program pages. These are optional – if you don’t add one, a stock one will be used.
Banners must be:
• Less than 800kb
Thumbnails are what show up next to programs when a keyword search is performed in the “What do you want to learn about?” search field.
Thumbnails must be:
• 300x300px (1:1 ratio)
• Less than 200kb
Along with the preset image types, programs can also have multiple embedded images. These images only show up on the program’s page. They must be jpegs, but otherwise do not have size restrictions; however, larger images mean longer webpage load times, so we recommend not exceeding 500kb. Reusing your Content Block image also works well.
WARNING: unlike preset image types, embedded images require you to click Submit for Review when finished. Failure to submit for review means changes will not be approved for posting to the live site.
