** Images can fool the eyes... or draw attention...

Images can benefit the visual learners in your classroom! There are three basic web image types - .jpg (or .jpeg), .gif, and png. .jpg or .jpeg - Short for //Joint Photographic Experts Group// ** The JPEG compression algorithm is at its best on photographs and paintings of realistic scenes with smooth variations of tone and color.

**.gif - Short for //Graphics Interchange Format// ** GIF is another of the graphics formats supported by the Web but limited to 256 colors - best for line drawings or non-realistic paintings.

**.png - Short for //Portable Network Graphics//** PNG is the third graphics standard supported by the Web (though not supported by all [|browsers]).



**Pixels -** **Short for //Picture Element,// a pixel is a single point in a graphic image.**

Note: Look at your monitor... those are actually pixels that you're looking at when looking at your monitor - millions of pixels make up the pictures that you see on your screen! 75 pixels (or dpi) x 75 pixels (or dpi) = 1 square inch.

The picture below is 75 px x 75 px ( 1 inch x 1 inch) Take the same photo and enlarge it to 300 px x 300 px Take the same photo and enlarge it to 600 px x 600 px What happens to the pixels as you enlarge the photo?

Your assignment: Go to Google and download 10 images that may relate to your projects - While looking for the images - please note: Size of image - don't download the 'thumbnail' Image should relate to you subject matter

To download the image - 1. Find the image...look at the size... 450 x 449 - click on the image to get the original picture - Image should appear in the middle of your page - Hold the control key (this is the 'right click' on the mac) and click on your mouse. A drop down menu will appear - scroll down to 'save this image as' 3. Another window will appear... save the image in your image/named folder

We will be using these images in iPhoto and later in iMovie.
