Using Comments field on files in Finder

If you select a file in Finder and use the 'Get Info' function, there is an editable field called 'Comments'. If any data is typed into this field, does that data remain with the file, even if you move the file to a different source? For example, if I am looking at a JPG file within Finder, and I add a brief description of the subjects or location of the picture into the comments field, will those comments still be there if I have burned the file to a CD, email the file to someone on a Windows computer, copy it to a thumb drive, etc.?

My purpose for asking this question is this. I have thousands of family photos, some dating back over 100 years, that I will be scanning in the near future. Once scanned, I will be sitting down with my mother and aunts to review these photos/files so we can determine who is in those pictures, where they were taken, when they were taken, etc. I will not have most of this information available to me at the time I am scanning them, but I want an easy way to attach this information to each picture as I review them with my mother/aunts. I also want to be able to eventually distribute the digital files to other family members, but most of them don't use Mac (their loss, I know... LOL!). I don't think that using Photos for Mac, Picasa, or a third party app to sort and label is going to be an option. 30 years from now, who knows what technology will be available, so I want to keep this process as simple and generic as possible, so they can still be accessed in the future.

Will the comments field work for this purpose, or do you have any suggestions for a better way to permanently attach this information to the JPG/picture files? Thank you so much for your help! 🙂
