Hellooo there. :) I was messing around in photoshop a little while ago, and I came up with this easy icon. I, for one, am happy to say... YAY CURVES! Don't be hatin on my curves. You'll need photoshop CS, yeah.

Background Layer
So, start out by opening your image of choice. You don't want it too dark, so if you're screencap is one of those really dark ones, brighten it up somehow. You don't have to do this, but I sharpen the full image twice. It looks nice, I promise. Crop it down to icon size.
Background Copy
Duplicate the base layer, and go to Filter >> Blur >> Guassian Blur >> 0.3
Set this to soft light.
Selective Colour
I wanted to lighten up the main colours of the icon.
Go to Layer >> New Adjustment Layer >> Selective Color
================
Reds:
Cyan: +66
Magenta: +20
Yellow: +16
Black: -44
Neutrals:
Cyan: -8
Magenta: 0
Yellow: -6
Black: -20
================
Set this to screen with an opacity of 35%.
Curves Layer
It's looking a little too dark now. Also, I know that when I brighten it, it'll be too contrasted. Using curves, I'm going to brighten it without letting a lot of contrast come out.
================
RGB: (Click to see image)
1st Point;
I: 186
O: 182
2nd Point;
I: 57
O: 97
================
Set this layer to an opacity of 72%.
Colour Fill Layer
Create a new layer. Using the flood tool, fill it with #87B1CB. Set this soft light.
Colour Fill Layer
The soft light layer sort of washed the icon out, so we need to bring the colours out. Create a new layer. Using the flood tool, fill it with #FFA800. Set this saturation with an opacity of 44%. However, by moving this layer below the blue soft light layer, you can get
this.
Texture Layer
Paste
this texture (by lovelamp) onto a new layer. I erased the parts that would cover Jennifer's face. Set this to screen.
Text Layer
Grab the text tool and create a new text layer. I used dearJoe: 18pt, Strong in white. It's a bit hard to read, but it says, "I'm friends with Madonna?!"
Brush Layer
Then I scribbled onto a new layer, and placed it over the text. If you make your own scribble, leave it at normal with an opacity of 43%. If you copy this brush onto your icon, set it to screen with an opacity of 100%.
Confused on the layer order?
Look here. And you're done. :]
