Compressing images in Microsoft PowerPoint

edtechhe

When creating PowerPoint Presentations we frequently forget to optimise images that we have included in the presentation. This results in a large file size, which may be too large to email or use up unnecessary student download limits. Through the use of the Compress Picture option, it is possible to optimise all images in a presentation at one time.

Using the Compress Picture approach, I compressed an PowerPoint presentation with an original size of 21.9 MB to 3.5 MB, without loss of quality for onscreen viewing.

Reduction in file size possible by using the compress picture option in PowerPoint.

The following video demonstrates the use of the Compress Picture option in PowerPoint. This feature is also available in Microsoft Word.

Image Sliders

Images Sliders (also known as image carousels or slideshows) consists of a series of usually between 5 – 10 static slides on a single topic. Slides include strong visuals and limited text and are a great way to introduce new concepts. Image Sliders support the Mayer’s 12 Multimedia Principles by:

• chunking content down to bite sized components
• combining text and appropriate graphics to help communicate key concepts
• allowing the user to control the pace of the presentation.

There are a variety of simple tools that can be used to create image sliders including:

• PowerPoint
• H5P
• Articulate Storyline.

The following is an example of a slider created using H5P that can be embedded into web sites and Learning Management Systems.
