There are lots of scripts that will manage a database of FHG (and/or HFS), but if all you want is a randomized list of 50 or so gallery links, you could use Excel or some other spreadsheet to do that. Just add an extra column and insert the Random function into the first field in that column, then you can use the Fill Down command to put random numbers into the entire column. Now you sort the whole sheet using the random number column as the sorting key and you can grab 50 links of your newly randomized list.
