Adding JPEG Comments

MaPiVi is a photo organizing software which can be used to add comments to JPEG files (always take a backup of your photos as this software works on it directly). However, MaPiVi is no longer being maintained actively. Another graphical tool which can be used for editing JPEG comments is XnViewMP. Originially written for Mac, binaries are now available for major linux distributions.

The linux commands "wrjpgcom" and "rdjpgcom" (provided by "libjpeg-progs" package) can be used for reading and writing comments to JPEG files as well. Other command line based tools that can be used are ExifTool by Phil Harvey (exiftool) and Exif Jpeg header manipulation tool (jhead).
