Try always to send an image with your item - it helps attract attention and means we don't have to use a generic image which might not be suitable. If you send more than one, and we can use them to introduce more variety into the item in consecutive issues. 

Note: Visitor stats show that an item's biggest impact (in terms of number of clicks for more information) occurs in the first two issues in which it appears – after that it drops dramatically. So the ideal time to publish is two weeks ahead of time, rather than a month, or six weeks.
