Following on from a recent comment in the 'Working Boats at Stoke Bruerne 1966' topic, I thought I would let you all know of one way of archiving your photos where you will be certain it will be saved for future generations.
I would encourage all of you to upload / submit photos to Geograph ( http://www.geograph.org.uk/).
This whole website and its collection of over 4.3 million photos (as of today's date) is being archived for the future by the UK Web Archive project (part of the British Library) http://www.webarchive.org.uk/. Also, as part of the Geograph submission process, your photos are located precisely on ordnance survey mapping, and you can add as many words to describe each photo as you wish. Photos of all dates are welcomed.
Of course when you have done this you can always post a link to them on this forum.
Another option available to everyone is to donate their photos to their local County Record Office. Of course, ideally, accompanying the photos there should be a record of where the photo was taken and the date. If the photos are slides, this can be done fairly easily by writing on the slide itself.
One other possibility in the future may be for moderators of this forum to agree with the UK Web Archive to archive this forum, of course !
