If you were on a Mac, I'd tell you that you could try File Juicer:
File Juicer doesn't care what type file you drop onto it; it searches the entire file byte by byte.
If it finds a JPEG, JP2, PNG, GIF, PDF, BMP, WMF, EMF, PICT, TIFF, Flash, Zip, HTML, WAV, MP3, AVI, MOV, MPG, WMV, MP4, AU, AIFF or text file inside, it can save it to your desktop or to another folder you choose.
For Windows I wouldn't even know where to start. Sorry.
NOTE: If there are no privacy concerns involved, I'd be happy to extract your images with File Juicer on my Mac for you, if you can make the file(s), folder(s) or directory(ies) available on a free FT service like Dropbox.com or YouSendIt.com.
Your photos are actually on your hard drive:
- Windows XP: C:\Documents and Settings\[User Name]\My Documents\My Pictures\Adobe\Digital Camera Photos
- Windows Vista/7: C:\Users\[User Name]\Pictures\Adobe\Digital Camera Photos
