The easy to use API that allows me to access my photos without any hassle of dealing with different APIs like java-imageio or opencv etc. I have been using this product since last 3 years now and there was never such an issue where i had to complain about it as compared to others products which are not so user friendly sometimes! Nothing much but just try out its free demo version first before you buy it because some features might be missing from your final purchase package. Accessing our photo's has become very simple by utilizing JDelijavaImage Library api.
