The most pertinent issues are:
(1) split has no default second argument, so the $_ needs to be explicit.
(1) at the least under unix, you could get an error trying to rename . and .. (the current and parent directories). To avoid that, replace the readdir with
grep !/^\./, readdir
(2) but, just in case there are yet more files in the directory that you don't want to rename, you might consider instead:
grep /^\d+\.gif/, readdir
(3) the '.' operator in the arguments to rename will not produce a literal '.' as has already been hinted at.
(4) it is possible but suspicious that you expect to have a mount point at '/temp_gif' ... should this not be './temp_gif'?
(5) if so, then when that is corrected, the fix suggested by others of putting the relative or full path in front of the arguments to rename will become able to function.
