[RS] 2004-07-27: Also, in plain [Tk] (but documented only for [Img]), 
you have access to the partial images of an animated [GIF]. 
This code was enough for me:

 package require Img

 proc anigif file {
    #-- returns a list of images from the given GIF file
    set index 0
    set results {}
    while 1 {
	if [catch {
	    image create photo -file $file -format "gif -index $index"
	} res] {
	    return $results
	}
	lappend results $res
	incr index
    }    
 }

#-- Testing (dumping the animation phases, one next to the other, into a text widget):

#-- Testing (dumping the animation phases into a text widget, and an animation):
 proc lcycle listName {
    upvar 1 $listName list
    set res [lindex $list 0]
    set list [concat [lrange $list 1 end] [list $res]]
    set res
 }
 proc every {ms body} {eval $body; after $ms [info level 0]}
 set file [lindex $argv 0]

 pack [text .t]
 set images [anigif $file]
 foreach img $images {
    .t image create end -image $img
 }
 .t insert end animated:
 set id [.t image create end -image [lindex $images 0]]
 every 100 ".t image config $id -image \[lcycle ::images\]"

  # Here's a slightly more minimal-but-generalizable form, applied to a canvas:
  proc animate_in_canvas {canvas gif} {
    foreach img [anigif $gif] {
       lappend ::id_list [.c create image 0 0 -anchor nw -image $img]
    }
    every 150 ".c raise \[lcycle ::id_list\]"
  }

  pack [canvas .c -height 300 -width 300]
  animate_in_canvas .c [lindex $argv 0]
