Make sure your gs command in ps2gif has "-dNOPAUSE -dNO_PAUSE" in it - that
stops it from pausing at the showpage.

My ps2gif has the option of -density xxx, where xxx is the pixel density
(default 72, can be set to 300 to match GMT plot default resolution).
I've included my version in this message.

No idea - I make animated gifs that are viewable in "xanim" and Netscape
using a program called "gifmerge". (http://the-labs.com/GIFmerge).  To
get them in order: gifmerge `ls -1 *.gif | sort -n | awk '{printf "%s ",$1}'`.
