    Hi arunmep,

    For me your question can have two diferent meanings.

    The first one is that you want to search for text in the image itself, in which case the sugestion given by the Anonymous Monk is valid. You shuold search for OCR on images.

    The second possible meaning is that you want to look for strings in the file content itself, not in the image. In this case I would recomend Image::Magick. $image->Get('Comment'); will return what you want.

    Are you asking whether it's possible to search through text that is visible in the image, or text that is embedded in the image file itself, amidst the binary file's contents (think: steganography)?

    print substr("Just another Perl hacker", 0, -2);

    Yet another interpretation of your question is that you are looking to read EXIF data. See Image::EXIF

    And even another possible interpretation ... use the linux "strings" utility.

    It's not Perl, but "strings myimage.jpg" will yield all strings of printable characters. Like: 

    *I7K
dbn^
"S3t0
VePz
|2`j
]C<v(
eH=BZ!
