Every microstock contributor knows, that some themes are selling much better in some months of the year – and those are seasonal themes, like Christmas, Easter, Halloween… You should start selling those several months before – for example with Christmas themes you should start already in August (November is too late – most of the designers works on Christmas cards already in summer / autumn and they need fresh photos).

List of the most important holidays

I think, that you should have some seasonal images in your portfolio, they are selling well, but dont forget on others global themes, which generates some income during the whole year.
