Text too small?
All browsers allow you to enlarge / reduce the image but each browser does so in a different way. In Internet Explorer for example, if you click on 100% (near the bottom right corner) the image will be enlarged to 125%, clicking again gives 150% and the third time it reverts to 100%.
An alternative way is by using the keyboard combinations "Ctrl +" to enlarge the image and "Ctrl -" to reduce it. These key combinations should apply across all websites regardless of the web browser being used.
