The recipe should display IPTC captions if there are such captions in 
the pictures, and if the PHP installation has the iptcparse() function 

You can try on your wiki one of the pictures from the demo page, they 
have such captions (except the third one). If the caption appears then 
your PHP supports the feature.

To test if your pictures have IPTC tags, you can upload them to the demo 
page and see if the caption appears.

Note that there are many IPTC tags, this one should be the "Caption" tag 
-- other tags are ignored.

Also note that this is not the same as EXIF tags, a different way to 
annotate pictures and to read the data in PHP. One would use the EXIF 
"Comment" tag to set some caption or comment, but the current recipe 
only shows IPTC caption tags.
