Images can be added to your toolkit's banner to include your organization's logo. To add an image to the toolkit banner, it must be a publicly accessible link.
Follow these steps to put images in your toolkit banner:
Upload the image on a publicly accessible website. We recommend using Imgur to upload your images.
Copy the image address once the upload is complete.
Add the image to the banner:
In the banner code section, use the following Markdown syntax: 
Replace image.jpg with the image address you copied from Imgur.
Replace [alt text] with descriptive text for the image.
To adjust the image size, append "#", followed by the desired pixel size, and then "px" to ensure proper scaling.
For example: (image.jpg#100px)
Check how the image looks in the live preview section below the banner settings.
Make any adjustments if needed, then click ‘Save’ to apply your changes.
