With File Juicer you can:
Extract images from a PowerPoint slide show.
Extract images from PDF files.
Extract the images from Safari's cache.
Extract attachments from email archives.
Extract Flash animations saved in .EXE files.
Juicer was made just for the first purpose, but it turned out it could do a bit more
Those are examples. Juicer does not care which type file you drop onto it, is searches the entire file, and if it finds a JPEG, PNG, GIF, PDF, BMP, Flash, or WAV file inside, it can save it.
This means that it works not only on Safari's cache files, but also Internet explorer, FireFox, Mozilla and OmniWeb.
It also works on files made with the other applications in Microsoft Office.
Windows .exe files are complicated, but File Juicer searches the entire file, and if the image or animation is not compressed or encrypted, it can extract it.
This is often the case for self playing Flash animations or Flash games, which have been saved in .exe format to make them simple for Windows users to run. Unfortunaltely this made then unusable on Macs.
Juicer does not extract any kind of image from any file type.
If the image, sound or animation, is not stored intact in one of the formats mentioned above, File Juicer can't find it. This is the case for images stored inside QuickTime movies, Adobe InDesign files and images inside Flash animations.
The email feature has only been tested with Apple Mail.
Flash animations, often play in QuickTime Movie Player, but sometimes you need to open them in your web browser from the File menu, and sometimes they play only from the website they belong to. This depends on the design of the animation.
