Hi Pepedog!
From what I gather/understand, the recent dime-day-listing hiccup we had here on Auctiva wasn't a matter of too many images on the server. It was a executing issue, they tried to tidy up a little something in the software and the walls, unfortunately, came tumblin' down.
Most of those of us on here I believe 'prune' our images periodically, out of courtesy to the auctiva folks. The reason you are seeing the images still is most likely due to you seeing an 'old' version of the page - that's where the 'clearing cache' thing comes from...it makes sure you see the newest version of the page, and not the old.
As watchinu mentioned, (assuming you use internet explorer) you can clear your cache by going to 'tools' menu at the top of the screen, then 'internet options' - you'll be looking for 'delete cookies' or 'delete files'...click that. Then you'll be looking for another button that will be beside something like 'days to keep pages in memory' or something to that extent...clear that too.
After that, you *should* get the newest version of the page. Hope this helps!
