Don't have time tonight, but maybe you have seen my dancing chicken spray, below is how I made it. If you have a few pictures you might be able to make an animated spray if you are willing to mess with the picture quality. You'll have to disreguard the steps reguarding decompiling a .gif; sorry I don't have the time to rewrite & test the instructions now.
1) Download an animated .gif file that you want to make into a animated spray.
2) Download VTFEdit:

3) Download GifSplitter:

4) Open your .gif with GifSplitter
5) Check the 'Auto fill and create the output directory' box
6) Hit 'Split Now'
7) Download GIMP:

8) Open all of your frames in GIMP
9) For each frame, click: Colors> Color to Alpha> Ok
10) Then hit: File> Save As> Select File Type> TarGA Image> Save> Uncheck BOTH Boxes> Save
11) Open VTFEdit: File> Import> Navigate to the Folder Where All of Your Frames Are> Select All of Them> Open
12) A new window should open. Uncheck Generate Mipmaps, and also uncheck Generate Normal Map if they happen to be checked.
13) You may have to mess with the resize method, maximum width, and maximum height if your final file is too large.
14) Click 'Ok'
15) Now you are ready to save it; save it first to your desktop, and then check the file size, if the VTF (Valve Texture File) size is over 120KB it will not work in-game. If it is under 120KB, you're good to go (Step 17).
16) If your file size is over 120KB, you can change the image size (See Step 13). Or you may have to delete some frames, then return to Step 11.
17) Once you get the right file size, move your VTF to: C:/Program Files/Steam/SteamApps/YOUR USERNAME/team fortress 2/tf/materials/VGUI/logos, and: C:/Program Files/Steam/SteamApps/YOUR USERNAME/team fortress 2/tf/materials/VGUI/logos/UI.
18) Open Team Fortress 2> Options> Multiplayer> Import Spray> Go to: /tf/materials/VGUI/logos, and select the VTF you just made> Open> Apply.
19) Now you're ready to go, just hit 'T' in-game and your spray should appear.
