My perception of the keyword problem is that if you have more than one keyword, it will not get picked up correctly.
eg. this image (keyword value "Cornwall")
http://www.pbase.com/image/23322465
is found by the image search
but this image (which has keyword value "Scotland, Forth, Bridge, Railway")
http://www.pbase.com/image/27958638
is not found by a search for "Forth"
Anyway i imagine its a relatively easy fix so i'll assume it will come along sometime
