Fair Use requirements

Please respect the limits of the Fair Use rules as follows:

include no more than one Fair Use image per page
upload a low-resolution version. The image is scaled to 250 pixels by the infobox, so a more detailed version is not justified
make good faith efforts to find a free version
if the author is known, please ask permission, and respect their wishes if you get a "no."

Usage

This template is for explaining the Fair Use rationale for using possibly copyrighted photographs for aircraft articles under the auspices of WikiProject Aircraft.

Usage is: {{Non-free aircraft image|article name|optional parameter}}. Optional parameter is the word no which adds the following comment:

Additional rationale: The aircraft depicted in the image was never produced and/or no intact examples of this aircraft remain in existence today, therefore creation of an equivalent free image is impossible.

There is a further named parameter |image has rationale=yes which will stop the message box in the lower part of the template from being displayed.

Therefore, the fullest usage is: {{Non-free aircraft image|article name|no|image has rationale=yes}}
