I have about 300 image from an event that were taken with four different cameras and I would like to put the images in the order they were taken. However the clocks on the cameras were not working correctly and therefore I can't just sort the files using the 'Date when created' field. Is there a software that will allow me to show all the thumbnails then click and drag the various files where I want them so that I can then rename them from 1 onwards so they are named in the order I want them? I am using PS Elements but it doesn't seem to work. Thanks!
