Attribute for <IMG ...>
LOOP = INFINITE | -1 | # of loops

<IMG 
SRC="../graphics/moonflag.mpg" 
DYNSRC="../graphics/moonflag.mpg"
LOOP=INFINITE 
ALT="Astronauts on the moon">

which gives us

You can specify a finite number of times for the movie to loop. This code produces a movie which loops ten times:

<IMG 
SRC="../graphics/moonflag.mpg" 
DYNSRC="../graphics/moonflag.mpg"
LOOP=10 
ALT="Astronauts on the moon">

which gives us

The problem with specifying a finite number of loops is that it is difficult to predict how many time is necessary to make sure the user will see the movie. For example, the movie in this example is way down near the bottom of the page. Even though the movie looped ten times, most users will not be down so far on the page before it is done. (It is worth noting that with some browsers, you can click once on the movie and it will run again the specified number of loops.) Either loop infinitely with INFINITE, control when the movie starts using the START attribute, or, best of all, use the CONTROLS attribute to give the user control over playing the movie. Don't use LOOP in the same tag as CONTROLS. There are inconsistent results as to which attribute takes precedence.
