two hints:

1.) do you use $wgUploadDirectory in your LocalSettings and set it to 
another dir than the expected ~/wiki/images ?

2.) do you use the apache-user in command line? different users, 
different permissions! perhaps your command-line-user has write-perms 
while apache-user not. try 'chmod -R 777 images images/math images/tmp'. 
if this works, reduce permissions or ownerships to what you raelly need.

after all a had a also a problem with the standard-pathes to latex's 
dvipng (i dont use imagemagic), but that's another story ...
