 Okay I have more pictures but these are property inspection ones in jpeg.
 For this set ST_Resize using percentage doesn't seem to work:


 {{{

 ST_Resize(rast,0.5,0.5)
 }}}

  for any of them regardless of if I have outdb or indb.


 However if I do pixel size like

 {{{

 ST_Resize(rast,100,100)
 }}}


 That works fine.

 I'm not sure if it's related to: #2182 and possibly a windows 2008
 specific issue.

 I'll check on my Windows 2003 64-bit server to verify it happens on that
 as well:

 Any rate:

 {{{
 raster2pgsql -F -Y -R C:/photos/*.jpg inspection_pics_outdb | psql
 }}}


 {{{
 raster2pgsql -F -Y C:/photos/*.jpg inspection_pics_local | psql
 }}}

 {{{
 SELECT version() || ' ' || postgis_full_version();

 -- outputs --

 }}}


 {{{
  -- works --
 SELECT ST_Resize(rast,200,200)
 FROM inspection_pics_local
 WHERE filename='PHOTO_1_20080101_121112.jpg'
 }}}

 {{{
  -- returns a black image --
 SELECT ST_Resize(rast,0.5,0.5)
 FROM inspection_pics_local
 WHERE filename='PHOTO_1_20080101_121112.jpg'
 }}}


 I'm attaching one of the problem pics this one is public record
 inspections so no issue attaching pic.
