1. Open up the picture you want to be placed in the photo, I chose a picture of my dog sleeping on my bed.
2. Select the " Rectangular Marquee Tool " and select a nice rectangle over the image that you would like to add into a photo.
Once you have selected a part of your image, lines should appear in a rectangular formation like this.
Now when you have that selected press and hold CTRL + C then go to File -> New and click OK
When a new document opens, press and hold CTRL + V and the selected part of your picture should appear
Click on the "Background" Layer and fill it in with a gradient or black, I used a gradient.
3. Now create a new layer, and select the pencil tool and choose around, 13 pixels depending on your picture and make an outline in *white* around your picture like mine.
This is an optional step but, with the pencil tool, add a few more pixels on the bottom of the image so its fatter then all the other outlines.
4. Now merge both layers together by holding CTRL + E - Once that's done, hold down CTRL + T to rotate/re-size your picture.
Now this is pretty much your decision, resize and rotate your image around until you like it. With some rotating and re-sizing this is what I got.
5. This is an optional step but it will make your photo look a bit 3D-ish
Edit -> Transform -> Perspective - Once a box appears that surrounds your image comes up, play around with the squares on the border of the box and you should get a 3D-ish result.
6. Right click on the layer and click on Blending Options and click on " Dark Shadow " and use these settings.
7. This is an optional step - Edit -> Transform -> Rotate 90 CW
Now go to Filter -> Distort -> Shear and use these settings
Now go to Edit -> Transform -> Rotate 90 CCW
Here's my result!
Here's an example of the tutorial combined.
