How to set a Image as a background in a folder

It involves making a new desktop.ini system file for that folder, and changing the attributes for that folder.
First, select the picture you want for that folder. It should be sized 815 x 685, or you will get tiles (of course, if you want tiles, use a smaller pic).
You can use your photo editor to crop and/or resize the pic appropriately.
Note the address of the pic. You will need that.
                                                                
Create a folder (in Documents) to store the desktop.ini file you will make, because it will replace the current system.ini of the folder it's in.
Now, open your notepad. Paste the following code into it.

[{BE0981 40-A513-11D0-A3 A4-00C04FD706EC}]
IconArea_Image ="C:\your picture location.jpg"
IconArea_Text= 0x00000000
Make the following changes:
The first line has spaces in it. Remove those spaces.
In the second line, put the address of the pic you will use, in the quotes.
The third line is the color of the folder text. Use light colored text for dark pics, and dark colored text for light pics.
Some color codes you can use. Feel free to use others, if you know them.

Black - 0x00000000
Pink - 0x00FF99FF
Purple - 0x00FF99FF
Red - 0x00FF0000
White - 0x00FFFFFF
Save the file as: desktop.ini
Save as file type : All Files
Save it in the storage folder you made.
Copy the desktop.ini file you just created, into the folder you want to change.
It should replace the one in there.
Go to START and RUN
Type: attrib +s "C:\Location of your folder"
The location of the folder you want to change is in the quotes.
Click OK (or Return)
Open your folder, and the picture should be there!
If the desktop.ini files shows in the folder, you can right-click it, select Properties, and make it hidden.
Please note, this only changes the folder you put the desktop.ini file in, not all of them.
