Sitemap Generator Forum

I am new with xml-sitemaps and use the program to create the sitemap for my photodatabase.
A typical excerpt from my sitemap would be:

<image:loc>[ External links are visible to forum administrators only ]</image:loc>
       <image:caption>Herbie Hancock </image:caption>
     </image:image>
</url>


Which EXIF/IPTC information from the photos does xml-sitemaps use to create <image:caption> ?

I have the problem that some of the photos do not have text in this field, even though the photo contains all the information.

Secondly, how is it possible to use  the automatic extension of my sitemap to get further information (for example <image:title> ) ?

Finally, the validate xml sitemap with the appropriate SEO tool returns the following report, which sounds slightly negative:

Schema validating with XSV 3.1-1 of 2007/12/11 16:20:05

Not recognised as W3C XML Schema or RDDL: html

and so on ...

Hello,

it uses "alt" or "title" attribute of corresponding <img> tag that includes the image on page.
