Seller plus account holders on eBid get up to five free pictures hosted on their listings. Quite often you really only need one or two views of the item being sold, but don’t waste the facility. There’s nothing to stop you putting pictures of other items, or general advertisements into your spare picture slots. Just make very sure that it’s clear what you’ve done.
Suppose you have a cup and saucer for sale, and you’ve put a couple of pics on. If you have another item that you think would appeal to the same sort of buyer, you can add a picture of that too with a suitable caption. Use your favourite image handling software to write “more items in my shop” or whatever across the picture and add it to the listing. Remember to also put a brief explanation on your listing, such as “pictures 4 and 5 are of other items available in my store at time of listing at storename.ebid.net” for example. Use your imagination! Cross-selling isn’t a strong element of the eBid layout, so make sure you do your best to bolster that aspect. And don’t waste those free pics!
