og Until now i use "smileys" mechanism to add custom pictograms into my wikipages. To make them upgrade-safe i put the definitions into /conf/smileys.local.php (as stated on the DW website) and the images itself into /lib/images/smileys/local/ (create this directory). Therefore i can distinguish between base files and my ones. So, if this is the way to do it, i would add this as tip on the DW website, but before i'd like to here from you if there is a better way...
