Hi Katy,
Are you talking about an active auction? I'm not sure exactly what you're trying to do...Here are easy instructions on how to change pics:
1) Locate your listing in your Saved Listings folder, make any necessary changes, and save.
2)Check the box next to your updated listing in your Saved Listings folder and click the “Get html” button.
3) Copy the html in the popup box.
4) Locate the item on eBay and click the "Revise Item" button.
5) Click "Edit Description" then click the "Enter your own html" tab.
6) Paste the copied html in place of what's there and save your changes.
As for the first part of your post, are you positive you saved everything? If so it should be there. Regardless, if you don't want to use it, just do not click on the seller details dropdown box after choosing a template.
If I'm not getting it, I'm sorry, maybe ask something more specific??
Just a little postscript...Auctiva is EXTREMELY easy to use once you have everything set up how you want it. The tools are all there, to use or not. The problems come in when you have to correct existing auctions.
