Hi all

I've been asked to write something to pull jpg/jfif files out of a binary file. I've had some limited success with my hex editor and I want to try it in perl. From my reading the picture stream starts withs 0xFFD8 and ends with 0xFFD9. The idea is that if I can pull everything out from between these markers we should have a valid jpeg image. I also suspect there are multiple jpegs within the binary file and they also each contain a thumbnail.

So my first question is can anyone point me in the right direction for extracting a block out of a binary file between 2 markers ? Once I get this working I think it should be quite straight forward.

Thanks in advance
