• Open Adobe Photoshop by going to the apple in the upper left hand corner of the screen.
  
  
• Go to File.

To Crop an Image:

• Open the appropriate picture by going to File and then Open.
  
  
• Select the crop tool which is located by holding the mouse button down on the Rectangular Marquee Tool (The Rectangular Marquee Tool can be found in a skinny rectangular box that contains a bunch of buttons. The Rectangular Marquee Tool is the button in the top left corner of the long skinny rectangular box. It looks like a square made from a dotted line). The crop tool is the one that is the furthest on the right. It looks like a square with a diagonal slash through it.
  
  
• Once you have selected the crop tool, select the part of the picture you want to save as a web picture. If there are multiple pictures, select one picture at a time.
  
  
• When the image is selected with the crop box around it, double click the mouse inside the box or hit the return key. The image should now consist of what was inside the crop box. If you are not satisfied with the image, you can always go to Edit and then choose Undo to undo the cropping.
  
  
• Go to File and then Save As.
  
  
• If this image will be used on a web page, it needs to be saved in your personal WWW directory.
  
  
• Select JPEG as the format for your image and enter a name. Make sure you add a .jpg at the end of the file name. This marks the photograph as a JPEG image.
  
  
• Your image is now saved. The original file will be closed and the only file that will be open is the new image that you just saved.
  
  You can repeat these steps as many times as needed.
  

To Rotate an Image:

• To rotate an image, make sure the correct image is opened.
  
  
• Go to Image, and then Rotate Canvas.
  
  
• There are 4 options. You can play with the different options until you find what you want.
  
  
• Save the image by going to File and then Save.

To Compress an Image:

• To compress an image in you need to either reduce the resolution of a picture, save the picture as a compressed jpeg, or reduce the number of colors in the picture.
  
  To reduce the resolution in Adobe Photoshop:
  
  • Load the image.
  • Uner the menu bar, select Image and then Image Size.
  • After Image Size has been selected, a screen will appear. On the screen there is a box entitled Resolution. Type in a smaller number and hit enter. Usually, the resolution is set to 72. The size of the image will shrink as well as the space the image takes up.
  
  To save the image as a compressed jpg:
  • Go to File and then select Save.
  • In the Save box, type in the name of the file. Make sure you add a .jpg at the end of the file name. This marks the photograph as a JPEG image.
  • Then under Format, select JPEG.
  • Hit Save. Another box should come up. In this box, you can change the quality number to a smaller number or you can adjust the little triangle with the mouse. WARNING: if you lower the quality number or if you move the arrow, you can lose the quality of the image and you will not be able to restore it! This process will not always lower the amount of space the image takes up, but it will make the image faster to load.
  
  To change the amount of colors used in a picture:
  
  • Select Image from the Menu Bar.
  • Then select Mode, and then Indexed Color. A screen will appear. Under the palette, make sure Adaptive is selected. Then, you can either LOWER the amount of pixels being used in the Color Depth box, or you can LOWER the number in the color box. WARNING: if you lower the amount of pixels or colors, you can lose some quality in the image and you will not be able to restore it! This shrinks the amount of space the image takes up, but not the size of the image. You can also hand pick the colors you wish to delete. To do this, go under Image, then Mode, and then Color Table. To delete a specific color, use the mouse to point to that color and then hit the mouse button, the control key, and the command key simultaneously.

  Trouble Shooting:

• You need to flatten your image. You can do this by going to Layer on the Menu Bar. One of the last selections is Flatten Image. Select Flatten Image to flatten the image.
  
  
• Go to Image, and then Mode to see if RGB color is checked. If it is not, select RGB color.

Now, you can try and save the image as a JPEG. Make sure you add a .jpg at the end of the file name. This marks the photograph as a JPEG image.
