Why a free donation?
A legitim question, on internet everything is free available. For a great part it is.
To keep a website like this running in best performance, costs a lot of time and money.
The last thing is because of cost for renting webspace, the domain-name registration fee, software, hardware and internet-access.
Also my photo equipment cost a fortune.In the circumstances i use my equipment, it need more specialistic maintenance. Thats why i ask to all statisfied visitors who viewed with pleasure a voluntary donation. If you are not statisfied with this website, you don't have to pay.
