If you have ever wanted to rename a sequence of photos in windows 7 so that you could change the names from things like img989.jpg to something nice like my holiday photos.jpg then there is an easy way to do that in seconds.
When you have batches of photos to add to your website it is beneficial to use sensible and preferrably unique file names which are descriptive of the photo, but even just having file names with your keyword description as a set will be helpful.
So, what you do is highlight all the photos you want to rename as a sequence.
Press F2 on the keyboard or right click on one of the highlighted images and choose rename.
Press enter and then all the files will name.
Then when you rename one file all the rest will rename in a sequence with a bracketed number after them.
Here is an example, select the images
and then rename one of them and press enter or click away
