When choosing an image's file format, size matters

When you are creating a custom presentation, keeping your file size small becomes a real challenge. The key to success is to use the proper picture type and be aware of the differences in file formats. When you want to use stock photography or clip art, keep these principles in mind: 1. Low-resolution (72 dpi) JPEGs are your best bet for photos. 2. For illustrations or clip art, stick with the WMF, which gives you smaller files than most other options for clip art, plus the flexibility of editing them directly in PowerPoint. If you are a designer who creates you own images, you will probably still want to rely heavily on JPEGS for most of the photos you import into an overall graphic.
