I'm trying to build the Google Sitemap for Images with BWP custom module.
but, I'm NOT able to build that.
The BWP is permitted ONLY 4 type attributes.
The Google Sitemap for Images needs an attributes such as below.
<image:image> <image:loc>xxx</image:loc> <image:caption>xxx</image:caption> <image:title>xxxx</image:title> </image:image>
How can I build that attributes ?
