So if we have any kind of document file that contains an image, if we locate the header and trailer, we can recover that image from the document. So here the scenario is that I have a Microsoft Word file and there is an image in that file, so we have to carve that image out from the Word file. In the above figure, we can see the raw hexadecimal data that forms the Word document. Within this block of raw data, we can search for the JPG file signature to show us the location of the first JPG image.

This location is very important and should be noted for future reference. So now that we have our file header, we need to find the file trailer. The same method is applied to find the trailer. Note that the offset value is not in the same place as it is for the file header. This is because we want to know the offset of the end of the bytes and not the beginning. Now we have the header and trailer of a jpeg file and, as we previously said, between the header and trailer is the data of a jpeg file.

Now we copy the whole block of data with header and trailer and store it as a new file. The entire jpg file will be highlighted in blue. This block of data now needs to be copied into the clipboard so that it can be stored as a separate file. After that it will prompt you to confirm that you want to proceed.
