I received a surprising email from Dreamstime this week that read as follows:
SR-EL sale - ID - Immediate action required

This image (that I cannot show you anymore) is of Big Ben in London at night with double decker bus light trails in the foreground. The image sold for $1,000 and I received $600.
Here is another London image with light trails i took on the same trip
That sure moved my monthly earnings up in a big way and will be very hard to beat in the future!
