[flexcoders] Re: Image Loader COMPLETE event wont fire for some images

[toofah_gm]

Tim,

Thanks for your help on this.  I feel like I am getting a little closer, but 
would like to get full understanding so that I can make a good decision on how 
to proceed.

The 2880 limit seems to be related to the problem, however it is interesting 
that this limit only seems to affect transparent images, or at least I haven't 
hit a limit yet for non transparent images.

Also, I am using FP10, which is supposed to have higher limits.  Do you know if 
this is dependent on the SDK that the app is compiled with?

If I change the image to "http://www.mangumfamily.org/pedigreeLargeBook.png";, 
which is 3764 x 2610 with transparency...it doesn't load.

"http://www.mangumfamily.org/pedigreeLargeBook2.png";, which is the same image, 
saved at 2880 x 1997 with transparency...loads great.

"http://www.mangumfamily.org/pedigreeLargeBook3.png";, which is the same image, 
saved at 2885 x 2000 with transparency...does not load.
This seems to prove that there is some sort of 2880 limit still with 
transparent images.

Interesting thing is that "http://www.mangumfamily.org/backgroundOriginal.jpg";, 
which is much larger, 4200 x 3188, but has no transparency, loads just fine.

Does anybody have some good understanding on this issue? or can you point me to 
some better documentation on such?

Thanks!

Gary
