John,

On Unix/Linux or Cygwin you should be able to do something like:

   find res_1 -name '*.tif' -print | xargs --max-args=50 gdaltindex \
              data/jamaica/tileindex_res_1.shp

Basically, this is using the find command to collect the list of names
(instead of wildcards which max out on commandline length limits)
and piping the list to xargs which will invoke gdaltindex on up to 50
names at a time.

Good luck,
