Can I include images, links or videos in my notice?

Yes

In the text editing bar click on the Insert multimedia icon (blue background icon with a white "M"). Once the gallery is open, select the image you wish to insert by checking the lower right box of the gallery and click Attach selection.

If you have not previously uploaded the file to the multimedia gallery you can do it directly from here by clicking on the option Add file at the top right. Remember to select the proper File Format. In case it is a video, in the YouTube Video Code option you must paste the part of the URL of the YouTube video that appears after "=".

You can add as many links as you need from the option Notice buttons and assign a URL and a different name to each button.
