Especially as we are making available more than 20,000 high resolution photographs (we are adding at the rate of 1,000 per months) our costs are very high so we have no option but to include advertising.
We have two main commercial sponsors: Google and Amazon.
If you buy from Amazon (US, Germany, France, The UK or Canada) it would really help us if you used our site to link to Amazon. You can also help by using the Google ads to exit our site but only do so if you are interested in what is being advertised.
