Marlene, you pointed out right, if I delete some dodgie picture of mine, so
as I delete a coments with it.

What I would do, if I re-shot a picture and delete a hopeless one, I would
copy/paste a coments what got for it to remember perhaps compare them
with a new coments.

An even better strategy is to do a new upload.  In your notes for the new
image, include a link to the original ... and some words about your artistic
intention for the new image (what changed from the original). 

In addition, edit your notes for the original and just add the link to the new
image (no other changes there) ... that way, you have everything that was
said about the original ... plus new comments, advice about the new image. 

You don't loose any information, comments, advice from friends ... We don't
loose any information about your progress as an artist.
