When it comes to photo’s I’ve not brilliant but I’ve learnt a couple of things one is if your item is a dark item take it against a white background if your items is white use a black or dark blue background.
We do have 5 slots for photos so that great as we can do an overall photo then do close up of specials bits. Show the reverse side and sometimes even the inside of an item, the top and/or side. So the potential customer can see as much as possible of the item.
I find I take far more photo’s than I use I tend to choose the best one’s I can manage. Natural light is great.
I would also suggest trying to using other social media sights to promote as well
There’s craftjuice and we have a craftjuice thread where we all vote for each other items once they get 5 votes craftjuice promotes our item onto twitter and facebook as well.
I would also suggest google+
Here are links to help you see what they are like
In the Showcase part of the forum there are many different threads you can join in where we agree to promote each other’s items like the weekly listing thread and others. These helps to expand your reach to new potential customers.
