Our version of mediawiki is a bit old and does not have latest look&feel options for galleries
I also had to modify the CSS (using mediawiki:common.css page) to avoid grey background on images, and to adjust individual image caption text size to 12px
I cannot use the standard "caption" syntax for the complete gallery, otherwise it's not possible to adjust the look&feel of this title according to EIG-wiki format
