Hi Phillip,

at the seemingly historic VAMP site it would appear there was at least
an attempt to port the Coppermine image gallery software to OpenVMS,
which uses the ImageMagick or GD image libraries. One of the listed
features of Coppermine is the generation of thumbnail and intermediate
size pictures.
