How to Remove the White Picture Background in PowerPoint 2007by Sam Foner
Microsoft PowerPoint is a presentation software application first released in 1989 as a part of the Microsoft Office suite of programs. PowerPoint lets users create custom presentations and slide shows using a straightforward graphical interface and simple tools. PowerPoint also allows you to customize the background images of your slides by using the preset textures and images or a picture from your own collection. Adding custom backgrounds is an essential part of using PowerPoint to its fullest.
Click on the "Design" tab from the menu at the top. Here, you can choose a preset theme for your slides. Text alignment and color will be automatically adjusted when you choose a preset theme. You can click on the arrows at the right of the Design menu to scroll through available themes.
Right-click on your current slide, then click on "Format Background..." to open the corresponding dialog box. Under the "Fill" menu, click on "Picture or texture fill" to access a full range of options. Here, you can add a custom image background or preset texture from the PowerPoint library. Click on "Apply to All" to apply your selected background to all slides in your presentation.
Click on the "View" menu at the top, then click "Handout Master" to customize the options for the printed version of your presentation. By clicking the "Hide Background Graphics" box, the slides will appear on a plain background when printed, though the actual computer presentation will retain color settings.
