I'm going to write a software (written for Windows) user manual for a software that we've written for our client. The manual needs to be as detail as possible. I'm going to use MS Word 2010 for writing the manual.
I plan to put lot of screenshots of various windows of the software and annotate on the screenshots. The page size needs to be A4 so that users can also easily take print out. The problem is, if I take full screen (the software takes whole screen, except the taskbar) screenshots and try to fit them on A4 size paper, many texts on the windows as well as annotations may be hardly readable.
To make things easier for the users, I'm thinking of putting links on the manual, and embed screenshots in the word. Clicking the link should open the linked embedded image in full screen. Users should be able to go back to manual with or without closing the image.
The problem is, I don't know if this can be done in Word. Is it possible? If not, is there any alternative/better approach?
