hi.... theoretically, if you list items on Ebay on Thursday night at about 7.30 / 8.30 pm time as a 10 day listing, they will achieve more money as they will end on a Sunday evening, the time when most people are looking, and the 10 days gives the maximum amount of time for the maximum amount of people to see your ad...
In addition to this, if you go to the Ebay "home" tab, go to Ebay pulse and select the category you want to list in in the drop down menu in top searches. This will give you top 10 key search words in the category - so fit as many of those you can (honestly) do in your title. The title only has to make vague sense - you just need as many hits as poss.
I would never personally list anything without a gallery picture, let alone a picture full stop. I would certainly not buy anything without a picture, unless it was something like a DVD.
I wish you luck - hope it sells well!!
