The question’s been asked several times around Tutorial9, “How do I download and install these custom layer styles you provide?”, and rather than answering the same thing over and over, I thought it was a nice idea to settle the issue once and for all in a convienent post for everyone!
Download Layer Styles for Photoshop
If you’re not familiar with layer styles, you’ll probably want to read through our Tutorial on Layer Styles in Photoshop.
Installing Layer Styles is actually just like Installing Brushes and Custom Shapes. Of course, the first thing you’ll need to do is actually download a Layer Style to use. Some examples would include our very own:
There are also plenty of sites out there that also offer Photoshop Layer Styles. I wouldn’t consider them nearly as important as Custom Shapes or Brushes (since they are usually replicated with ease), but they can be nice for speeding up workflow and making your life easier.
Make a note of where you save your files. We’ll need to find them in the next part.
How To Install
From Photoshop, find your Styles Palette, and select it. If it’s not visible, go to Window > Styles.
At the top right of the palette, there is an arrow pointing to the right. Click on this arrow to bring up a menu. From this menu, select Load Styles.
Now, simply browse to wherever you saved your styles, and load them. You’ll see them populate the Styles Palette, and can then apply them as you would any other Style preset.
That’s it!

Layer Styles in Photoshop
Will the layer styles be saved to the photoshop folders or will I have to keep the asl files wherever I loaded them from?
@muffins: You can manually move them to the Photoshop folder, which in some cases is helpful, as you can then easily load them from the drop down menu whenever you’d like to use them — rather than browse for the .asl file. Probably a good solution if you find you do a lot of resetting of your layers palette. However, simply loading them will not move any styles anywhere. They are loaded from the .asl file.
For reference, the default folder for Photoshop’s Styles is: Program Files > Adobe > Adobe Photoshop (version) > Presets > Styles.
Been using for quite some time but a good quick tutorial David.
Can the brushes be used with a Mac based photoshop?
@Lisen: Yup, should work fine in both Windows and Mac!
