[ale] detecting Adobe Flash content in static image files

[Jim Popovitch]

The problem I am finding with file is that it's not exactly accurate.

For instance, i have a .gif (GIF89a) that file reports as

  "Infocom game data (Z-machine 71, Release 17976 / Serial 33)"

And others:

  "PC bitmap data, Windows 3.x format, 432 x 215 x 8"
  "ASCII text, with CRLF line terminators"
  "x86 boot sector, code offset 0xd8, OEM-ID"   <------ file name
contained a ")" char


Which makes it really really difficult to script something like:

  find /var/www/images/ -type f -exec file {} \; | egrep -v
"(GIF|JPEG|PNG) image data"
