Flash Authoring, QE
I appreciate the help.
We are currently working on a way to handle these type of images better in Flash. In the mean time, please see below on how to fix these images.
1. open the JPG in Photoshop.
2. re-save as a JPG with a different filename.
3. import the new JPG.
These steps correct the JPG header bytes and allow Flash to correctly read them from XFL files.
In your case specifically, after step 2 you should use the bitmap properties dialog in Flash Library panel to reimport the image. After importing you may or may not see a change on stage. Please save the file, close, and reopen the file. The images will appear on stage correctly.
Thank you for bringing this to our attention and thank you for the quick response.
