SWF bitmap compression Photo (JPEG) not showing

I have this library.swf with a few bitmaps inside. Some are .png with transparent areas and some are flat .jpg.
In both cases, when I load the SWF and export targeting Flash, I can see only the bitmaps which are exported with compression Lossless (PNG/GIF).
Is there support for bitmaps using Photo (JPEG) compression?

In case it helps, here's the output of my haxelib list:
actuate: 1.38 [1.40]
box2d: [1.11]
hxcpp: 2.08.1 2.08.2 2.08.3 [2.09]
jeash: [0.8.7]
nme: 3.2.0 3.3.0 [3.3.1]
swf: 1.07 1.10 [1.11]

Thanks.
