All images are described using English language captions and keywords and all have a unique 8 digit image identification number. To find what you are looking for, enter one or more keywords in the search query box at the top left of the page and click the 'Search' button. Note that keywords should always be in singular rather than plural form. You may also search by image number or photographer name.
To search, enter a keyword in the search box and click the 'Search' button. This type of search will often display broad rather than specific search results. For example:
This search will display all images including the word elephant either in the caption or as a keyword including elephant seals, elephant shrews and elephant birds. For more specific results you should use additional keywords:
This search will display subjects including two elephants, two elephant seals and two elephant bird eggs. The more keywords you use, the more specific the results will be. For example:
For best results, you should use keywords describing species names, color, natural features, habitat, behavior or location. Note that typing successive keywords results in a so-called 'and' search displaying those images that include all search words within the caption or keyword list.
Advanced search at the left of the search results page allows for more advanced searching techniques using boolean, phonetic, proximity and wildcard searches.
Displays images of elephant portraits as the "and" operator retrieves images with both keywords.
Displays images of elephant portraits but excludes elephant seals from the search result as the "not" operator excludes images of seals from the results.
Displays images with keywords tiger and zoo as well as those with keywords lion and zoo. The "or" operator indicates that the search applies to images of either lions or tigers as opposed to images including both keywords lion and tiger. The parentheses clarify that the keyword zoo applies to either keyword within the parentheses rather than just the latter of the two keywords preceding it. Hence, tiger and zoo or lion and zoo, not tiger or lion and zoo.
Searches using two or more words result in images containing all specified keywords. To have the search engine treat the words as linked search words, you should surround them with quotes.
Single character wildcards (?) and multiple character wildcards (*) may also be used in keyword searches. This is especially useful when unsure of spelling. Please note that wildcard searches may take somewhat longer to execute.
Displays images with keywords such as lion, lioness, lionfish, etc. and also such keywords as play, playful, playing, etc. In general this is a "starts with" search requesting the display of all images with keywords spelled beginning with the letters prior to the * wildcard.
Displays images with such keywords as butterfly, mayfly, dragonfly or any other keyword ending with fly. In general this is an "ends with" search displaying any images with keywords ending with the letters following the * wildcard.
Displays images with keywords spelled beginning with ba and ending with g with any number of letters in between such as balancing, bathing, barking, etc. In general, a search like this displays images with keywords starting and ending with specified characters.
Displays images with keywords beginning with d and ending with g and with a single letter separating them. Matching keywords might include dig, dug or dog.
Another wildcard-like search tool is the "like" operator which may be used to conduct phonetic searches. This is especially useful if you are uncertain of the spelling of a given keyword, or if for instance you search for a specific keyword and your search yields no matching images despite a strong suspicion that there should be matching images in the archive.
