How to rearrange photos in Lightroom

How can I change the order of photo in grid mode of Library? Lets say I have photos A,B,C,D, in that order and I want to move the to the order of D,C,B,A, How would I do that.
Thanks

Go to menu: view > sort > choose however you want to sort them
User order = manually sorting the order

Thanks for fast reply, Ok I just tried that now do you drag the photo to its the new oder and drop it there? That what I just tried to do and the photo would not drop in to the new order.

Drag and drop the photos in the order you want them. You can do that in the "filmstrip" view at the bottom of the screen also.

For what ever reason I can drag the photos but can not drop the photo in the new locations.

I believe you have to be in the Library module, and in the Grid view for them to move around.

Yes, I was in the Library module and in the Grid veiw to move the photos. I can drag them but I can not drop them into a new order. Most be doing something wrong just do not know what it is.

You have to be viewing the lowest level folder or have 'include photos from subitems' turned off - it won't work if you're viewing a composite of a folder and its subfolders.

Also, pick the picture up by the middle of the image, not the area surrounding it.

I've been having the same problem. I try to drag an image and it just bounces back to the original place as though it were on a spring. The only way I've found around that is to make a Quick Collection from my catalogue; then I can move things around in the grid view.

Now that explains a few things. Thanks!
