While the flower and the close-ups are nice, I never understood why members post these high MPix images. They have to be strongly -- and badly --compressed jpgs in order to clear the storage size limit (2MB) thus enlarging them in a separate window will not give good quality. In fact, by reducing pixel size to max. 2000pix on the long axis and processing files accordingly, you can have images posted that appear tack sharp and have vibrant colours, yet still clear the 2MB upper limit.
Why do we have the storage limit? that is to avoid overloading our server and exhaust our allotted storage space, which would entail even higher hosting fees. We barely scrape by at present as the majority of the users seem to be fine with using the site and won't care about the expenses they incur. This is not a sustainable approach in the longer run and we will either have to clean out images or make subscription mandatory.
