:::hint{type="warning"}
This page / section pertains to **BrightAuthor Classic**, our legacy app. **BrightSign Author **is our latest app for managing content and players.

Development of BrightAuthor Classic has largely ceased and the app will eventually be deprecated and replaced with BrightSign Author.
:::

The Image Cache tab displays a list of all image files in your presentation. Selecting an image will preload it into player memory–it will then load and display much faster during playback. Note that the **Available cache** space is displayed below–you cannot exceed the allowed space with cached images.

:::hint{type="danger"}
Cached images are always displayed at their full resolution–they cannot be scaled up or down. Make sure the size of the image matches the size of the zone.
:::

You can preload up to 16MB of images. If an image is compressed (e.g. *.jpeg*, *.png*), then it will use more memory than its reported file size in Windows/Mac, and BrightAuthor Classic will show this larger file size when you add it to the **Image Cache** list. Since Bitmaps (*.bmp*) are not compressed, the reported file size of a Bitmap image accurately represents how much memory it will use.
