Using Photoshop

• 1). Open Photoshop, then click the "File" menu and select "Open." Browse to the image to break into smaller parts, and double-click the name of the file, opening it onto the Photoshop canvas.
  
  
• 2). Click the "Rectangular Marquee Tool," the square made of dotted lines second from the top on the "Tools" pane. If you see another tool in this spot, right-click it and select "Rectangular Marquee Tool" from the fly-out menu.
  
  
• 3). Position the cursor near the top-left of the image, press and hold down the left mouse button and drag to break the picture into its first part. When the blinking dotted lines appear, press the "Ctrl" and "C" keys simultaneously to copy it.
  
  
• 4). Click the "File" menu, and select "New." Enter "Part 1" into the "Name" box, leave the other options as their defaults and click the "OK" button. Press the "Ctrl" and "V" keys simultaneously to paste in the picture. Click the "File" menu, and select "Save." Click the "X" on the picture's tab to close it or leave it open as desired.
  
  
• 5). Click back to the original image, and repeat the "Rectangular Marquee Tool" on the next section of the picture. Repeat the "New" process off the "File" menu to create a file for that piece. Continue until the picture is broken up entirely. When closing the original picture, if Photoshop asks to save it, click "No."
  
  

Using Paint

• 1). Open Windows Paint. Click the Paint button in the top-left corner, then click "Open." Navigate to the image to break up and double-click the file, opening it on the Paint canvas.
  
  
• 2). Click the "Select" button on the ribbon, then choose "Rectangular selection." Outline the section of the picture to cut into its own piece. A dotted blue line surrounds the selection.
  
  
• 3). Click the "Crop" button on the ribbon, breaking the picture into the piece.
  
  
• 4). Click the Paint button, then click "Save As." Type a new name for this part of the picture so as not to override the original whole image. Click "Save."
  
  
• 5). Reopen the original image, and repeat the process to break it down into the next piece.
  
  

Using Publisher

• 1). Open Microsoft Publisher, and click the "Blank 8.5 x 11" button. Click the "Insert" tab at the top of the screen.
  
  
• 2). Click the "Picture" button, locate the picture to break up and double-click its file name. When it opens on the Publisher page, click the picture to open the new pink "Picture Tools" tab.
  
  
• 3). Click the "Crop" button on the tab. The picture gets four small angle borders. Drag a border to form the size of the new piece of the picture. Click anywhere off the image onto the Publisher page to perform the crop/cut.
  
  
• 4). Reopen the image again through the "Insert" tab's "Picture" button. Perform the crop again on the next section, and align that image with the first, so eventually you'll have a page of pictures broken up from the original.
  
  
• 5). Click the "File" tab, then click "Save As." Type a name for the file, and click the "Save" button.
