I've imported a number of bitmaps to use as buttons in a Flash movie. The
preview perfectly in Flash (MX) itself but once exported/published their
quality degrades. I've tried setting jpeg compression to 100% with no effect
(and the movie size remains the same) and I've changed the bitmap properties in
the library to lossless png/gif, again with no effect. The movie is displaying
at high quality.

What am I doing wrong, how can I get by bitmaps to display correctly?

Any help would be appreciated.

I think I've worked out what was going wrong (although I'm not 100% sure). I'm
new to Flash and after importing the bitmaps I deleted the source files, I
assumed that the FLA file would keep the bitmap data intact but perhaps this
isn't the case. I think that the bitmap data in the FLA file was being degrade
as I played with compression options and couldn't update itself as the source
files weren't there. Could this be the case?

I've re-imported the bitmaps and left the source files in place and things
seem to be working correctly now.

P. Jay, once you import an image file in to Flash that is it, the FLA will
always have that original data. The compression options affect only the version
that is placed in the SWF.

It must be something else!

Hmm, I don't know then, altering the JPEG compression didn't make any
differance to the quality or the resulting swf file. Having re-done it things
seem to be work properly again! Probably something to do with my inexperience!

Thanks,
