Generate and edit public URLs for assets

In the Library in Optimizely Content Marketing Platform (CMP), you can generate public URLs for your assets, which lets you share them inside and outside the organization.

When you generate a URL, CMP provides a randomized GUID. To customize this, you can add a custom domain and edit the URL to make it more on-brand.

Generate a public URL

Go to the Library.
Select or upload an asset.
Go to the Image Information tab for the asset.
Click Generate Public Link.
Click the Copy icon to copy the link, or follow the steps in Edit a public URL to customize the link.

Add query parameters

CMP lets you resize images by appending parameters to the image's public URL using ?.

You can use the following parameters:

width – Defines the width of the image in pixels.
height – Defines the height of the image in pixels.
action – Determines how the image should be resized or manipulated to fit the target width and height.
- Crop – Resizes the image while maintaining aspect ratio to fill the dimensions, then crops any excess. Cropping is centered based on center_width and center_height.
- Padding – Resizes the image while maintaining aspect ratio to fit within the dimensions, then adds padding if the aspect ratios do not match. The padding color is determined by the color parameter.
- Border – Does not resize the image initially and places the original image centered within a canvas of the specified width and height. If the dimensions are smaller than the original image, it crops the image; if larger, it adds a border. The border color is determined by the color parameter.
color – Specifies the background color to use for padding or borders. Accepts hexadecimal color code (like FF0000 for red or 000000 for black). It can also be the string “transparent” for transparent padding if the file format supports it.
center_width – Specifies the horizontal focal point for cropping as a percentage (0-100) of the image width. 0 is the left edge, and 100 is the right edge.
center_height – Specifies the vertical focal point for cropping as a percentage (0-100) of the image height. 0 is the top edge, and 100 is the bottom edge.
crop_x – Specifies the X coordinate of the crop region's top-left corner in pixels.
crop_y – Specifies the Y coordinate of the crop region's top-left corner in pixels.
crop_width – Specifies the width of the crop region in pixels.
crop_height – Specifies the height of the crop region in pixels.
