Photos & Clip Art
Images can be added from the Insert tab on the Ribbon. Go to the Insert tab, and on the left side, note the "Illustrations" area. The first button in that section is titled "Picture." When you click on the button, a navigation dialog box will appear. You can select any image on your computer, and it will be placed on your slide.
As usual, it will be in a placeholder box. Just as you can with shapes, you can resize and rotate the image with the placeholder handles.
Notice that when the picture is selected, a new tab appears at the top, titled Picture Tools: Format.
On the left side of this Ribbon tab, there are tools to Adjust the image. Next to that are Picture Style options, which allow you to choose a variety of frames.
One of the improvements in PowerPoint 2010 is the "Adjust" group in the "Picture Tools: Format" tab:
An interesting new feature of PowerPoint 2010 is the "Remove Background" button. This feature allows you to remove the background from an image—even a complicated background. Before, you could only remove a background if it was a single color, different from any other color in the image. The "Remove Background" feature is much more intelligent.
First, place a picture you want to do this to. In the example below, notice that the dog is in an image with grass.
What if I want to remove the grass only? Just go to "Picture Tools: Format," go to the "Adjust" group of buttons on the left, and click on "Remove Background." You will see this:
Change the handles on the inside box so they surround only the item you want to isolate. Then just click outside the image. So long as the item you isolated is fairly different from the background, you will see the background disappear:
As you might notice, the clipping is not perfect—but it can be very good. You can now see the slide background all around the dog.
It is still possible to do this the old way; in the "Adjust" group, there is a menu called "Color"; in that menu, near the bottom, you can see a selection titled "Set Transparent Color." This tool, however, will only remove ONE solid color, making it a poor tool for a complex background—but an excellent tool for a simple background:
If the image you have is too bright or too dark, you can do some rough, quick corrections to it by changing the Sharpness, Brightness and the Contrast.
Color allows you to change the Saturation (intensity of colors), Tone (shift to red or blue), or to Recolor an image to one specific hue.
One more useful adjustment tool is "Artistic Effects." This allows you to quickly achieve effects similar to those possible in programs like Adobe Photoshop.
See a few before-and-after images—and then try out the effects for yourself!
Another nice way to change an image is with Picture Styles. These allow you to choose a variety of frames, borders, drop shadows, and other effects which make the pictures appear special. Just click on the image, then click on the style you wish to apply.
Just as with Shapes and Text, Pictures also have buttons for Fills, Borders, and Effects. These can also be used to create custom Picture Styles.
Other Picture Tools
Under the Arrange section, you can change the layer of the image, align images with other objects, group images with other objects, or rotate & flip the images; finally, you can adjust their size or, more importantly, crop the image so that parts of it do not appear.
If there is any clip art you would like to add, it is probably available in Office 2010. When you click on the Clip Art button in the "Insert" tab, a new sidebar, or pane, appears on the right side of the Window.
To get the widest variety of clip art, make sure that "Include Office.com content" is checked. Next, type a keyword for an image type that you want to find in the "Search for" box, and then click "Go" (or hit the "Enter" key). In a moment, you should see a number of clip-art images appear below. Inserting the clip art is easy: just click on it, and in a moment, the image will appear in the middle of your slide.
Once you have inserted the clip art, it can be treated much the same way as a picture. Some clip art, however, has no background, as in the example above.
