Powerpoint Image Basics - Formats and Finding them Online
The following article is a transcript from a our video product, "Intro to Powerpoint XP."

PowerPoint is a great program because it lets you easily add digital photos to your presentation. However, the world of computer graphics and digital photos can be a little confusing as there are many different photo file formats, and different ways to get those pictures onto your computer. Let’s discuss some of the basics of “digital imagery” – just the stuff you need to know before placing pictures onto PowerPoint slides.

The file formats
There are two main picture formats you will run across. They are both picture files, but use different “compression schemes” to keep the file sizes small and manageable.

1. ".jpg" … This type of file is a basic photograph. Jpeg compression takes advantage of the many colors and color-gradations found in a typical photograph. Most photographs are saved in this file, and this is the image type that your digital camera produces.

2. ".gif" … This format is all over the internet. It’s optimized for graphics with few colors and little color change (like clipart and cartoons). This format is used a lot in webpage design – in fact, most of the graphics and logos on this site are actually gif files!

Finding Pictures Online
Where can you find pictures for your PowerPoint presentation? If you have a digital camera, you can take snapshots and download the .jpg images onto your computer. Another great place to find pictures is on the internet!

By far, the best place to search for suitable images is at Google.com. Google is fast becoming the most popular search engine on the internet (even beating out the big ones like Yahoo and MSN) because it has a very simple interface and some powerful search tools. One of these tools is the “Google Image Search” button. When entering a search term, try clicking on the “image” tab and Google will find and generate little thumbnails of appropriate pictures.


Click on the thumbnail and you’ll be taken to the webpage where the picture resides. You can then save the image by “right-clicking” with your mouse, and then selecting “save image.”

When you saving images off your camcorder or the internet, I recommend saving them into the same directory that your PowerPoint “.ppt” file is located. This keeps everything organized. Also, it’s hard to extract a photo already embedded in PowerPoint back to its original form, so it’s nice to have the original picture on hand and easy to find.
