#' @title
#' post /search/images
#'
#' @description
#' Submit a search request for `images`
#'
#' @param con list; required: TRUE; BrAPI connection object
#' @param descriptiveOntologyTerms vector of type character; required: FALSE; A
#'    list of terms to formally describe the image to search for. Each item
#'    could be a simple Tag, an Ontology reference identifier, or a full
#'    ontology URL.; default: "", when using multiple values supply as
#'    c("value1", "value2").
#' @param externalReferenceIDs vector of type character; required: FALSE;
#'    External reference identifier(s) to search for. Could be a simple strings
#'    or a URIs (use with `externalReferenceSources` parameter).; default:
#'    "", when using multiple values supply as c("value1",
#'    "value2").
#' @param externalReferenceSources vector of type character; required: FALSE;
#'    Source system or database identifier(s) of an external reference(s) to
#'    search for (use with `externalReferenceIDs` parameter); default:
#'    "", when using multiple values supply as c("value1",
#'    "value2").
#' @param imageDbIds vector of type character; required: FALSE; A list of unique
#'    database identifiers of images to search for; default: "", when
#'    using multiple values supply as c("value1", "value2").
#' @param imageFileNames vector of type character; required: FALSE; Image file
#'    names to search for.; default: "", when using multiple values
#'    supply as c("value1", "value2").
#' @param imageFileSizeMax integer; required: FALSE; A maximum image file size
#'    to search for.
#' @param imageFileSizeMin integer; required: FALSE; A minimum image file size
#'    to search for.
#' @param imageHeightMax integer; required: FALSE; A maximum image height to
#'    search for.
#' @param imageHeightMin integer; required: FALSE; A minimum image height to
#'    search for.
#' @param imageLocation list; required: FALSE; A GeoJSON Polygon geometry, as
#'    defined by GeoJSON (RFC 7946), which describes an area to search for other
#'    GeoJSON objects. All contained Points and intersecting Polygons are
#'    returned as search results. The coordinates are decimal values on the
#'    WGS84 geographic coordinate reference system. A coordinate position MUST
#'    be two or more elements. The first two elements are longitude and
#'    latitude, or easting and northing, precisely in that order and using
#'    decimal numbers. Altitude or elevation MAY be included as an optional
#'    third element and is  specified in meters.
#'
#'    The `coordinates` list MUST contain the following two elements:
#'
#'    * `geometry` as a list; required: TRUE; A geometry as defined by GeoJSON
#'      (RFC 7946). In this context, only Polygon geometry is allowed.
#'
#'      The Polygon geometry is described by exactly two elements:
#'        + `coordinates` as a list; required : TRUE; List of linear rings, where
#'          each linear ring is a list of at least four positions with the first
#'          equal to the last. The first linear ring specifies the exterior
#'          ring, and each subsequent ring an interior ring.
#'        + `type` as a character; required: TRUE; Literally specified as "Polygon".
#'    * `type` as a character; required: TRUE; Literally specified as "Feature".
#'
#'    The easiest way in R to construct the `imageLocation` list is to use the
#'    **geojsonR** package. The Examples section shows how to create a
#'    `imageLocation` list object for a polygon geometry.
#' @param imageNames vector of type character; required: FALSE; Human readable
#'    image names to search for.; default: "", when using multiple
#'    values supply as c("value1", "value2").
#' @param imageTimeStampRangeEnd character; required: FALSE; Time stamp to end
#'    the range for images to filter on. Coded in the ISO 8601 standard extended
#'    format, where date, time and time zone information needs to be provided
#'    (check for example https://www.w3.org/TR/NOTE-datetime).
#' @param imageTimeStampRangeStart character; required: FALSE; Time stamp to
#'    start the range for images to filter on. Coded in the ISO 8601 standard
#'    extended format, where date, time and time zone information needs to be
#'    provided (check for example https://www.w3.org/TR/NOTE-datetime).
#' @param imageWidthMax integer; required: FALSE; A maximum image width to
#'    search for.
#' @param imageWidthMin integer; required: FALSE; A minimum image width to
#'    search for.
#' @param mimeTypes vector of type character; required: FALSE; A set of image
#'    file types to search for, pattern to use "image/*" e.g. "image/jpg",
#'    "image/jpeg", "image/gif"; default: "", when using multiple
#'    values supply as c("value1", "value2").
#' @param observationDbIds vector of type character; required: FALSE; A list of
#'    unique observation database identifiers this image is associated with to
#'    search for; default: "", when using multiple values supply as
#'    c("value1", "value2").
#' @param observationUnitDbIds vector of type character; required: FALSE; A set
#'    of unique observation unit database identifiers to search for.; default:
#'    "", when using multiple values supply as
#'    c("value1", "value2").
#' @param page integer; required: FALSE; Used to request a specific page of data
#'    to be returned. The page indexing starts at 0 (the first page is
#'    `page = 0`). Default is `0`.
#' @param pageSize integer; required: FALSE; The size of the pages to be
#'    returned. Default is `1000`.
#'
#' @details Submit a search request for `Images`. Function will return
#'    either the search results (Status 200 for an immediate response) or a
#'    `searchResultsDbId` (Status 202 for both a saved and an asynchronous
#'    search).
