How Brightspot delivers images
When you upload an image to Brightspot, the image remains in its original form without any cropping or resizing. When a visitor views one of your pages that contains the image, Brightspot does the following:
- Determines the context required for the page.
- Crops, resizes, and otherwise modifies the image as required by the context.
- Delivers the modified image to the visitor’s web browser.
- Saves a copy of the modified image for subsequent visits to the page.
When cropping an image to a specific size, Brightspot crops around the original image’s center. In the following example, the image to the left is 594 × 370 pixels, and the sunset is to the far right. In some contexts, Brightspot needs to deliver the image cropped to 224 × 246. Because the default crop is around the image’s center, the sunset is lost.

To prevent such situations, you can set a focus point inside an image. Brightspot then crops the original image around the focus point. For example, if you place the focus point on the sunset, Brightspot applies the 224 × 246 crop around the sunset, keeping the sunset as close to the center as possible.
