Comment:

 {{{12799.diff}}} adds an optional {{{numberimages=""}}} parameter to the
 [gallery] shortcode.

 This parameter is named similarly to the {{{numberposts}}} attribute in
 {{{get_posts()}}}.

 If the {{{numberimages}}} parameter is set to a number greater than zero,
 then it controls the maximum number of images displayed by the [gallery]
 shortcode.

 Examples:

 {{{
 [gallery link="file" columns="4" orderby="rand" numberimages="4" id="256"]
 [gallery link="file" columns="4" orderby="rand" numberimages="4"
 include="263,264,261,260,259"]
 }}}

 In both cases, only 4 images (at most) will be displayed.

 The code on line 836-839 is only necessary because in get_posts(), when
 specifying include="", the numberposts parameter is ignored (it's set to
 match the number if items in include="").
