7 Ways to Reduce the Size of the Powerpoint File

There may be times when you need to present your 
measurement findings using Powerpoint. If you are not 
careful then Powerpoint presentations can quickly become 
very large files. Here are 7 ways to reduce your 
presentation size.

1. Insert pictures as files: don't copy and paste. Saves 
   space, especially if you use the picture several times 
   in the presentation.

2. Convert image files to jpg or gif as these are smaller 
   than other formats such as bmp. Use jpg for photos and 
   gif for pictures with large blocks of solid colour.

3. Generally your images don't need to be larger than 
   1024 × 768, as this is the most common resolution for 
   laptop screens and projectors.  If your image is just 
   occupying part of the screen you can make it smaller.  
   The smaller the images the smaller the Powerpoint 

4. If using PowerPoint 2002 or later, you can compress 
   images from within PowerPoint. Right-click the picture 
   then click Format Picture > Picture tab > Compress.

5. Embedding fonts increases the file size.  Think about 
   whether you really need to embed the fonts.

6. When finished use the Save As command and save the 
   presentation under the same name.

7. Disable the slide preview thumbnails.  Go to the 
   File menu, properties, Summary tab.  Clear the 
   Save Preview Picture check box at the bottom of the 
   dialogue box and click OK.  In PowerPoint 2007, from 
   the Office menu choose Prepare and then Properties. 
   From the Document Properties drop-down list, choose 
   Advanced Properties to find the Summary tab.

Measuring Bond Strength
   The speed at which heat moves between two materials 
   touching each other, shows how strongly they are 
   bonded to each other - according to a new study.

Bionic penguins take to the water - and the skies 
   Robotic penguins swim through the water as gracefully 
   as their living counterparts - the design could help 
   improve the grip of industrial robots.

Ocean-Going Robotic Submarine Returns
   Scientists are celebrating the first successful 
   deployment and retrieval in Australia of a 
   remotely controlled, deep ocean-going robotic 
   submarine. The submarine's sensors measure temperature 
   and salinity, as well a range of biological parameters 
   including oxygen and turbidity.

High-tech speed bump detects damage to Army vehicles 
   Researchers have developed a technology that detects 
   damage to critical suspension components in military 
   vehicles simply by driving over a speed-bump-like 
   "diagnostic cleat" containing sensors.  The speed bump 
   is equipped with triaxial accelerometer sensors.  The 
   system measures vibrations created by a vehicle's 
   tires. Damage is detected in the tires, wheel bearings 
   and suspension components by using signal processing 
   software to interpret the sensor data.
