hi all,
i wonder if i specify the same image map over and over again in the scene
description ....

e.g.
...
...
...
pigment { uv_mapping image_map {  "myfile.gif" interpolate 2 } }
...
...
...
pigment { uv_mapping image_map {  "myfile.gif" interpolate 2 } }
...
...
...
etc....

would it get loaded into memory several times or does povray detect this and
load the file only on first occurrence.

this is an important question for me since i generate the scene files
automatically from another program and i would have to change the approach
if the files were indeed loaded several times.

kind regards,
uwe

Yes, the image file could have changed in the meantime for example with 
the use of POV-Ray's file writing functions.

To avoid this declare the pigment once and reuse it.
