# Banner illustrations in Theme Builder

Banner illustrations are used to increase user engagement or announce overall product experiences.

## Default banner illustrations

A banner illustration is applied to a web page when there is a need to visually represent abstract concepts, reinforce branding, enhance user engagement, or maintain design consistency. Banner illustrations are theme-able, and adapt to the theme colors of your instance.

**Important:** Banner illustrations apply to Workspaces and are not supported in the Core UI.

## Custom images

Upload your custom images to Theme Builder to replace the default banner illustrations.

To override the default banner illustrations with custom images, upload each image individually. The size and format limitations for custom images are as follows:

|Field|Description|
|-----|-----------|
|Dimensions limit|w572 × h160 px|
|Format|SVG|
|File size limit|2 MB|
