You can use add safe-search options with this:
&ss={safe-search}
where {safe-search} is 0,1, or 2 corresponding to on, moderate, and off, respectively.
You can limit searches to a particular content-type by using this:
&ct={content-type}
where {content-type} is one of the following:
??? 0 for photos
??? 1 for screenshots
??? 2 for other stuff (art, drawings, CGI, and so on)
CHAPTER 2 ?– UNCOVERING THE MASHUP POTENTIAL OF WEB SITES 41
??? 3 for photos and screenshots
??? 4 for screenshots and other stuff
??? 5 for photos and other stuff
??? 6 for photos and other stuff and screenshots
You can also limit photos by a date range:
&d={taken-or-posted}-{from-date}-{to-date}
where {taken-or-posted} is taken or posted and where {from-date} and {to-date} are of the
form yyyymmdd. You can state one or both of the dates. For example:
&d=posted--20070702
&d=taken-20070613-20070702
Finally, you can search for photos with certain Creative Commons licenses by using this:
&l={CC-license}
where {CC-license} can be one of cc (for any Creative Commons license), com (for licenses
that permit commercial reuse), or deriv (for licenses that permit derivative works).
