No, no sequences. Here is an extract of Dave Baggetts ST picture
formats list:

---------- CUT HERE -------------------

 ...

<Spectrum 512 (Smooshed)>          *.SPS

   This format compresses Spectrum 512 pictures better than the standard
method.  There are at least two programs that support this format, SPSLIDEX
and ANISPEC, although the two seem to differ slightly in their interpretation
of the format.
   One point of interest: Shamus McBride deciphered this format without an ST!
 
1 word          5350 (hex) ("SP")
1 word          0 (reserved for future use)
1 long          length of data bit map
1 long          length of color bit map
<= ? bytes      compressed data bit map
<= ? bytes      compressed color bit map
----------
< ?  bytes      total

 ...

---------- CUT HERE -------------------

Hope this ends the discussion,
