How to transfer my images back to my nikon d90 from my PC?
Put my SD card into card reader(F drive) on PC to look at some practice images i took.saved them into a folder but i can't transfer them back onto my camera even after copy n pasting… On the LCD screen, the image amount has reduced as if the images are there BUT when i press playback i get "folder contains no images" what should i do?
You obviously haven't been reading or following this forum very long. Bad idea. If you want to make that card fail use it as a display device.
Find another display device because neither the camera or it's memory card are intended for this purpose.
Besides, if you are successful in getting photos back on the card the camera won't see them anyway because they are always slightly altered when uploaded.
Once you make ANY changes in the images, your camera (or any camera) will not be able to see them.
The LCD on your camera is only for checking your images after you shoot them so you can decide if you need to reshoot or not. It is NOT there as a viewing screen to show off your images.
Just format the card using the format feature on the camera and go back to shooting.
The work-flow is thus.
Shoot you photos
At the end of the day, copy all the images to your computer
Once safely on the computer, format the card, using the format feature on the camera.
Once you have 4 gb in image files on your computer, make a DVD back up disc and file it in your image library.
Plus one to both Jim and "Ace", it's really a one way street. Move photos off your card, BACK UP images to another drive or CD/DVD disc, then format the card back in the camera. Note if when you move images to PC an option pops up to "move images and then erase card" via the OS deselect that option, leave images intact on card until you are sure you have them safely moved over to your PC and backed up. Only then reformat the memory card in the camera you are using the card in. Reformatting memory cards in camera after each use is a good way to virtually eliminate all read/write issues in camera.
