I'd like to know the opinion of you fine people 
regarding an ethical question I have.

The scoop is that I own quite a few cels.  A 
number of people (including, I know, many people 
who are reading this forum right now) have been 
urging me to put a gallery online so that other 
people can see my collection.  I've finally 
decided that I'd like to take your advice, and so 
I'd like put up a gallery online.

But there is a problem.

Most of my cels, I bought from people on this 
forum, or from YJP, or from eBay, or from Yann's 
web site, or from Anime Chaos or Anime Asylum or 
Taro or other Internet dealers, etc.  When I did 
this, I always downloaded the "for sale" cel 
picture from the web site into my own cel records 
folder.  For, maybe, 1% of the cels I own, which 
I bought at Otakon or at other "hands-on" venues, 
I made my own scans.  For all the rest, I have 
swiped the scans from the "for sale" page on the 
Internet.

(Confession: If I've bought cels from you, and 
you used Java to disable the right-click on your 
scans, you may not rest easily;  I know how to 
easily work around that trick, and so I have 
always worked around that Java trick when I 
bought a cel from you, and I swiped your scan and 
downloaded it for my records).

If I re-scan all the cels I own, it will probably 
be (many) months before I can put a gallery up 
online.  If I re-use the scans (from other 
people) that I have, I think I could put the 
gallery up months sooner.

My question is:  is it OK for me to post in my 
gallery, the scans of cels that now I own, but 
the scans of which I swiped from YOU?

I really do want to do the Right Thing here, 
especially with death-threats and banning and 
other nonsense that's been going on lately....

Thanks for your thoughtful help!
