Fair use is not transferable, hence such images may not simply be used — each use must be re-analyzed.
The images are included to directly address the (educational) topic under discussion in the notes. No other known image exists that could be used (or it would have been). The use here is unlikely to have any affect on the market for, or value of, any copyrighted work.
All photographs by the author are available under the Creative Commons Attribution-ShareAlike 3.0 Unported License (Attribution: Dr. Paul Mullins, Slippery Rock University), to the extent allowed by law. (It's up to you to evaluate content of the image.)
To the extent possible, these images shows minimal detail of any copyrighted software and are believed to qualify in the context they are presented as "fair use" under U.S. law. (As noted above, my fair use, does not mean that your use is.)
Thumbnails are provided as links to images created by the author, or located elsewhere on the Web: Wikimedia Commons. In all cases, the image served from here is a substantially reduced, low digital resolution version of the original and are believed to qualify in the context they are presented as "fair use" under U.S. law. (Make your own.)
Some images were constructed using Microsoft PowerPoint and include clipart. As entire sets of notes could be constructed in PowerPoint and published in various forms, including as web pages, these images are believed by the author (who is not a lawyer) to be legitimate original works using a duly licensed product. Most textbook publishers seem to agree, as they typically make available PowerPoint notes (often with explicit guidelines for creating derivative works).
With regard to clipart, Microsoft may disagree, as they disallow the right to "grant your customers rights to further license or distribute the media elements". Further, this collection of notes might be interpreted by some as a "book" (whatever that is), and use of PowerPoint to illustrate the chapters in a book is not allowed.
Hence, I recommend that these images be replaced in any derivative work. To the extent allowed by law, presumably this includes at least the design or intended message, these images are available under the Creative Commons Attribution-ShareAlike 3.0 Unported License (Attribution: Dr. Paul Mullins, Slippery Rock University).
The sidebar image – in various resolutions – is a constructed image (see above) using clipart and displaying content of a Wikpipedia page.
This particular image is the composition of two public domain images from www.wpclipart.com
Used for educational purposes only: specifically to show how a laptop works connected to a docking station. Active software displayed includes FireFox spanning two screens, showing a Wikipedia article (on multiple monintors), and Microsoft Windows Display Properties dialog box for setting dual displays (with different aspect ratios for screens). No other image is known to exist displaying this set of circumstances. This is believed to be a "fair use" in the context used.
This photo shows a Motorola Droid with all of the screen blurred except for the indication that speech recognition software is working. The background, of which little can be seen, contains a Wikipedia article (in FireFox) on speech recognition.
Full screenshot at low resolution, showing examples of application and system software. Used for educational purposes only. No other such image is known to exist. This is believed to be a "fair use" in the context.
A composition of small portions of screen shots showing files size and data rates used in actual applications. Used for educational purposes only. No other such image is known to exist. This is believed to be a "fair use" in the context.
This photo of the microphone, webcam, and light sensor on a Dell Latitude includes a portion of the screen for context (size comparison). The screen shows HTML-Kit under MS Windows, but is heavily blurred and low resolution. No other such image is known to exist. This is believed to be a "fair use" in the context.
