Images
Although well-presented text alone can often make an excellent presentation, good quality and relevant images can be an important feature to enhance effectiveness in getting a message across.
For images there are three golden rules:
- use Insert | image instead of copying and pasting (which means you need some images ready – now if you’ve planned the presentation you’ll have those, won’t you?!)
- use images that are big enough to fill the required area without looking fuzzy or pixellated
- keep image proportions right – that means resize using the corner handles and not the middle handles.
As a general guide, a full screen image needs to be at least 800 pixels wide by 600 pixels deep, and preferably rather more. For a panel in a two-column slide, the minimum dimensions would be something like 350 pixels wide by 390 pixels deep.
Excellent images can be found at galleries on the web, and many are offered with permission for use in non-commercial ways. Visits to sxc.hu and morguefile.com may well be very rewarding as well as BBC archives and the Prelinger film archives for some interesting material from the past.
