select your image, go to the picture tool (format) tab.
Top left of this tab is an option called recolour, hover over this and at the bottom of the box is "set transparent colour" click this then the background and 'POOF!' Answered Dec, 19 2010

1 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.
2 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.
3 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. Answered Jan, 01 2011
