You explained - sort of - but that doesn't answer this question I asked. I can't even see the freaking _o.jpg files - or when I do, I see the file on my hard drive and not the one on auctiva. Why are they handled differently than jpgs on any other website? Why does opera ask me what to do with it? Why does the URL in my Seamonkey or Firefox show up as being on my hard drive? I've seen the same problem with other people's pictures on ebay's boards when they've had that _o.jpg stuff.
I don't work well online. Their system times out on me for one thing and for another I prefer to use Turbolister so I can leave it open and do what I want when I want without having to login/logout or get messages that you're getting timed out. I don't use ebay's SIY form for that reason too.
So what is that weird _o.jpg file?
I'm trying to figure out if I can use auctiva just as a picture host. I don't think so from what you say and the way I see things handled on my end. I don't need thumbnails and click to enlarge stuff. I do that myself. I would never waste the space or bandwidth uploading something directly from my camera and maybe then try to edit it. I have all the graphics software I could ever want.
