I too want to transfer pix from computer to Smartparts Photoframe

No, the Philips PhotoFrame has a USB flash drive connector, you can plug-in a flash drive and transfer the pictures from that. No cables needed.

Where can I find a remote control for my Smartparts digital picture frame SP104C?

You can't see pictures on the frame while it's connected to the computer. The frame is supposed to say, "PC Connection established..." If you go to My computer and look for your frame as a removable device, you can open it and view the internal memory of the frame. You can see all the pictures on the frame and delete them if you wish.

sounds like there was a power serge.  One of the suggestions would be to make sure you use the "safely Remove Hardware" tab on the tool bar.  The USB cable actually has power that goes through the line and can damage the flash memory in the picture frame.
your one hope would be to try another USB cable. 

The setup file is on the frame. Connect the frame to your computer w/ the USB cable. Go to MY COMPUTER. Look for your frame as a removable device and open it up. There is a blue icon called "setup." If you click on it, it will start to download to your computer. If you can't find it, you can download from Smartparts website at this link:

First install the application which you receive with the picture frame on your computer. Connect the frame with your computer by using the USB cable. Once you have connected the frame, you will be able to see an additional drive in "My Computer". Just copy the pictures from your computer and save them in that new folder.

In some software, which come with the digital frames will create a program by themselves after the installation. In these case, you need to open the program and then connect the photo frame to the computer. After connecting, you will see that the frame will synchronize with the computer and you will see that the program which you have already opened will show you the drive of the frame, where you can just transfer the pictures from your PC to the frame.

Your PhotoFrame does not have internal memory acording to the Phillips data sheet, therefore you need to load your pictures directly onto a memory card (one from your camera will proabably work.) If that isn't convenient, you can generally get a good price on a SD memory card which is supported by your PhotoFrame.

If you wnat to transfer pictures from your PC to the memory card and have a card reader, you can transfer the pictures in Windows Explorier from your PC to the memory card and then plug the card into your PhotoFrame. If you do not have a card reader, plug the memory card into the PhotoFrame and connect it to your PC using a USB cable (you may have to buy one as acording to the Phillips data sheet it is not supplied.) When the PhotoFrame is pluged in it will appear in Windows Explorier as a new hard drive, and you can copy your pictures to it.

I hope this helps,

Mike

To remove a picture, connect the frame to your PC via USB. you should see the frame appear as a drive, in my case,
36972 (E:)

open the drive as Explore, you can now see the pictures, and delete what you no longer want.

you can download the software from
http://www.smartpartsproducts.com/content/support/optipix/index.php

You have to first download the images to your computer and Save them in a folder. Then connect the USB cable from the digital photo frame to the computer and transfer the photos you want onto the frame. Some time you have to change the photos name to alphabetic order so you photoframe will display the pictures in the correct order.
