The only way I know of doing this is by using the listing creator tools. On the row where it has"Style Format Font Size" to the right of that you see the color choices and then a little yellow tab that does not look like anything I can describe! However it lets you insert an Auctiva image and you can then add your captions.
One warning however your image is inserted full size rather than having a super-size function.
Edit them to as small as possible while still viewing well. Cut and crop as much useless "noise " out of the pic as you can or your auction will load painfully slow for dial up users.
EDIT: This answer from Auctiva Mike D in November.
quote:
In order to add captions to your images, you need to click the "Manage Images" link under the "Images" tab within your account, enter your desired captions in the "Caption" field next to each image to which you'd like to add a caption, and then click the "Update Captions" button along the top of the page.
Once you have added captions to these images, when you select them to be used in a listing and click the "Display Captions" box, the captions that you entered on your "Manage Images" page will be displayed next to the appropriate images in the listing, as well as the preview.
However I have tried this before and it does not work for me. Possibly you will have better luck? Please let us know how you make out. As for Miss M I know you will tell us about in our epic!
