The world of images is HUGE!

There are so many ways of working with images and new programs and services are popping up all the time. It is important that you have a basic understanding of images, some of the programs used to manipulate them, and have some idea of how image creation/editing programs work.


Step 1: Defining image

  1. Open a WORD document and save it as:image-definition.your-name
  2. Center a header with your name, class period, and "Image Definitions & Types".
  3. Use your favorite browser to search for 2 different definitions of "Image".
  4. Typing the definitions on your WORD document - in your own words!
  5. Save the document

Step 2: Identifying image formats

  1. With your WORD document image-definition.your-name open,add a bold heading below your definitions named "Image Formats".
  2. Use your favorite browser again to find websites with different image formats.
  3. Select ten (10) image formats and type them on your WORD document.
  4. Try to add a description of how or where each file format is used.
  5. Spell check and save the document.
  6. Turn in your completed document to the "Image Definitions" folder.

Step 3: Image Formats and Sizes

Now that you understand a little bit about what an image is and some of the possible image formats, let's explore how different image types have different file sizes.

  1. Follow the teacher instructions to copy a bitmap image to your computer skills/images folder.
  2. Follow the teacher instructions to open the document in Paint.net and save it as a jpg, gif, png, and tif file.
  3. Open your images folder and look at the file sizes for each of the five documents you just saved.
    • Which one is largest?
    • Which one is smallest?
    • What impact does file size have on how the image appears?
    • Do you wonder which file type is best for different uses, like a website, a borchure, a picture frame, or an editing program?

Step 4: Resizing Images.

We just saw that the file type changes the size of the file. We can also change the image size so it is smaller, even with the same format. This is called resizing the image. We will do this in Paint.net.

  1. Open your jpg image in your images folder using paint.net
  2. Click the IMAGE menu tab, then select RESIZE.
  3. Make sure the "Maintain aspect ratio" box is checked.
  4. Click in the WIDTH box and type "250" - notice how the height changes automatically.
  5. Click "OK" and notice how the image on your screen changes.
  6. Click file: Save as: and add "-small" to the end of your file name...click "Save".

There you have it. You can now change the file type and the image size for any picture! Good work.


Step 5: Playing with Paint

You now have a very basic understanding about images and how to change their type and size. Let's now explore ways to create or manipulate an image. We will start with Paint.net, a program installed in all computers at the school.


Follow along as the teacher walks through the basic features and tools of Paint.net.

Create an image on your own

Now you have seen the basic features and tools....create something you can be proud of. Here are the requirements:

  1. Must be school appropriate
  2. Must have 2 text boxes
  3. Must have 3 different colors
  4. Must use at least 2 different shapes

  6. Turn in the completed image to the 'Coursework' drive, 'turn in' folder, your period, "Image Creation" folder

You have completed the assignments for Image Handling. Basedon time, there may be an opportunity to play with Photoshop, a powerful image editor.
