This is because the image smoothing (that you can't turn off, even if you uncheck the "allow smoothing" option for the image source in the library) in flash seems to smudge the images to the left and right by 1 extra pixel than it's current width. Resizing the image by +0.1 will make it look better (and avoid the 1 pixel border clipping issue that can also happen as it forces the boundry of the image to be larger), but the image will actually display 1.0 pixel bigger to the left and right, which can be a ripe pain if you're after pixel perfect alignments using actionscript to dynamically position elements. The -0.1 trick seems to work in most cases (at least, it hasn't failed me yet), it might even fix the alpha blending warp issue but I've not tested it with that yet. This keeps the image displayed at the exact same size so positioning with actionscript won't cause 1px overlaps as it can when you use +0.1 NB: I was hoping that the flash 7 player would fix all of these annoying habbits, but it didnt seems to, at least, not whilst playing flash 6 swf files. But I'm hoping they didn't impliment any backwards compatability bug fixes in this area due to all the wacky hacks people use to subvert the problem. I'm hoping that swf 7 files viewed through the flash 7 player won't have to deal with this issue. ps. Always check your image alignments in the web based flash view ( like in a browser) as opposed to the in flash "test movie" player, as this player is completly hopeless when it comes to dealing with bitmaps, so chances are any alignment issues you see here won't actualyl appear when viewed through the flash browser plugin.
