+ <para>
+ The optional <parameter>imageinfo</parameter> parameter allows you to
+ extract some extended information from the image file. Currently this
+ will return the diffrent <acronym>JPG</acronym> APP markers in an
+ associative Array. Some Programs use these APP markers to embedd text
+ information in images. A very common one in to embed IPTC <ulink
+ url="http://www.xe.net/iptc/">http://www.xe.net/iptc/> information
+ in the APP13 marker. You can use the <function>iptcparse</function> function
+ to parse the binary APP13 marker into something readable.
+ <example>
+ <title>GetImageSize returning IPTC</title>
+ <programlisting>
+ <?php
+ $size = GetImageSize("testimg.jpg",&$info);
+ if (isset($info["APP13"])) {
+ $iptc = iptcparse($info["APP13"]);
+ var_dump($iptc);
+ }
+ ?>
