Hi ​@ChfaAdmin, 

Welcome to Box Community, and we’ll help set a banner on your File Request page. 

Working with Custom Branding

Here’s how you would setup branding for your File Request:

1. Create a File Request on the folder as before  (If you need a refresher use this article: Using File Request to get Content from Anyone)
2. Click Edit to apply custom branding.
3. Select Theme to open Header Logo and Theme Color section
   • If your Box Admin has set a default logo and color for your enterprise, the logos will be visible. If not, the defaults will be ‘No Image’ and a no color icon .

Adding a Header Logo

1. Click + to start.
2. Click Add an Image and select the logo you would like to upload.
3. Click Upload.
   • Uploading a new logo does not make it a default for all your File Requests. You can still select different logos for different file requests
   • Images look best at 80 pixels height, png format, and transparent background.
   • Image files must not exceed 1 mb.
4. Next, let's select a color. Theme Color is where you will set the background color for the file request.
   • You can select any of the predefined colors or use the + icon to select a different color. You can use the HEX code to select a color.

• • You can add any number of custom colors to the palette. However, upon saving the form, all custom colors are deleted except the one you selected.
  • After selecting your logo and color, click Preview to review your updates.

      5. Click Save or Share to save your changes.

Here’s an example of a custom-branded File Request page from a File Request creator’s point of view
