rndCiv unit images

Hi

Ive got a hundred or so images done for rndCiv, and have a script
to produce the .png & .spec files, but when i try and run the client
it fails with....

(civclient:13834): Gdk-CRITICAL **: gdk_image_get_pixel: assertion `x >=
0 && x < image->width' failed

civclient: helpdata.c:951: helptext_unit: Assertion `num_allowed_units > 
0' failed.

there are only 64 units in the ruleset im using, and the game starts ok,
the client dies when i try to look up a new unit in help.

i don't want to run all my questions through this maillist, so if 
someone would like to mentor me on making image sets, then we'll have it 
done soon.
