For such questions, it is better to check the forums first and ask there rather than in the blog section. There is a thread re. current increased review times of editorial images (thread 31425). If your editorial images are time sensitive and newsworthy you can ask for priority review, otherwise you just need to wait patiently in the queue. It seems that the number of editorial images has increased significantly recently due to the Olympics, elections in Europe and the Queen's jubilee.
