Problem with 5 jpegs

Hi,

I'm developing a php script which will seek out all jpegs in a folder and
create a swf which cross-fades between them all in rotation.

It all works fine, except when I add more than 5 JPEGs to the swf. Ming
seems to generate the file but Flash simply refuses to play it. I've tried
downloading the results of the php script and playing it locally but no joy
there too.

Is this a known issue with swfbitmap? Would it make a difference if I used
PNG (DBL) files instead? I'm using the binaries from kromann, which fixed a
previous problem I had with ming and text on windows.

Is is possible to load an existing swf file in ming and use it like a
swfsprite etc?

I'm kinda in a bad place right now as the guy I'm developing for is
expecting this to work v.soon.

Thanks in advance

Antony
