Headshots are installed in folders named by PersonID in the OLT volunteer database and grouped in a folder hierarchy with no more than 500 sets of volunteers per folder. The folder hierarchy is as follows: "/HeadShots/500/" "/HeadShots/1000/" "/HeadShots/1500/" etc... e.g. Bob Hicks is PersonID = 1 PersonID 1 is less than or = 500 and so is stored in folder "/HeadShots/500/1/" Conor O'Hegarty is PersonID 1240 and his head shots are stored in "/HeadShots/1500/1240" The formula for the 500-level folder is Int((PersonID+499)/500)*500 The system currently shows only one headshot, based on a thumbneil with a name using the pattern "tn_*.*". If there is no file in the foldeer with this name template, then no headshot will be displayed. If there is a larger image with the same file name except for the "tn_", then the thumbnail will provide a link to the larger file. e.g. tn_1.jpg, 1.jpg, tn_bob.png, bob.png There are no limits to file sizes, but the current practice is: thumbnails are 150 pixels wide full size photos are approximately 100 kb in size
