Hi - you need an OCR package such as OmniPage Pro or Textbridge if you want to extract the text from an image file.
I have a copy of OmniPage Pro v9.0 which was given away free on the cover disk of PC Pro. If you send me a blank CDR I will copy it for you.
Current version of Textbridge Pro cost around £70. Not sure about OmniPage Pro but it has moved on a few version from the give away cover disk version. Now at v12.0.
