Multiply blending mode to PNG

I have a layer in Photoshop with multiply on, when I however save to web it loses the blending mode.

How can I keep multiply or achieve the same effect in another way?

Here is one thing you can do.

1. Copy the image you want to multiply. (CtrlA and CtrlC)

2. Make a new 'Black' color layer and click 'add mask'.

3. alt-click the Mask icon, so that you can enter to mask edit mode.

4. Paste your 'multiply' images in the mask (b/w) , and then invert it.

5. You will have a black layer with your multiply material masked.

6. You can adjust opacity of that layer to find best looking image. (30~40%?)

7. If you save it as transparent PNG file, you are done.

It is not perfectly same with 'multiplied image' , it will be somewhat dimmed, not that vivid enough, but it is quite useful when you need normal images or textures to apply on top of something.

Blending modes are not supported by PNG. All you get is alpha transparency. If you want something blended with the background, blend it in photoshop first, and save the flattened image.
