*How do you install Brushes into Photoshop?
1. Download or move the .ABR file to a permanent location on your computer. This could be into the Photoshop Brushes folder (full paths below) or a central location you create for Photoshop brushes. To place it in Photoshop’s existing brush folder, move or copy the .ABR file to:

Windows: C:Program FilesAdobeAdobe Photoshop CSxPresetsBrushes
Mac OSX: Applications/Adobe Photoshop CSx/Presets/Brushes/

2. Open Photoshop and select the Brush tool.
3. On the Options bar, click the down arrow beside the brush shape preview. This will open the controls for brushes.
4. From the brush control popup, click the right-facing arrow in the top right corner and select Load Brushes or Replace Brushes.
5. When the Load Brushes dialog appears, navigate to the location where you placed the .ABR file and then open that file.
6. If you chose the Replace Brushes command, Photoshop will remove any existing brushes from the Brushes palette, leaving you with only the newly loaded set. However, if you chose the Load Brushes command, Photoshop will add the new brush set to the end of the list of brushes.
7. Start brushing!

Also included in this set are the PNG images for each crack, in both high, and low resolution.
