There are many ways to share files such as pictures, videos, and documents from your HTC Desire to other PC or devices. You can share via Bluetooth, post to Facebook,  post to Flickr, send by email to Gmail, or post to Twitter, Picasa or Youtube.

In order to send photos/videos from your HTC Desire to Windows 7 PC via Bluetooth, it is fairly simple. Here are the steps that you can follow:

1. Before you can send files from your HTC Desire  to your Windows 7 PC, make sure your Bluetooth is on and ready to accept incoming connection. In order to check on your Bluetooth settings, go to Control Panel > Network and Internet > Network and Sharing Center and select Change Adapter Settings.

    

2. From there, right click on your Bluetooth Network Connection, and select Properties. Go to Bluetooth tab and select Bluetooth Settings. Make sure the “Allow Bluetooth devices to find this computer” is ticked. (You can switch it off once you have completed your file transfer) 

   
   You may want to tick “Show the Bluetooth icon in the notification area” in order for you to accept incoming connection easily. Click OK when you are done.

3. Next from your HTC Desire, go to HOME and select Photos. Tap the album where the photos or videos you want to share are in. Tap the Share button and then on the Share options menu, tap Bluetooth. Select the photos or videos you want to share and then tap Next.
4. In the next few steps, you’ll be asked to turn on Bluetooth on your phone and connect to the receiving Bluetooth device so the files can be sent. Tap on the “Scan for devices” to locate your Windows 7 PC. Once your PC is found, tap on it to send.

   

5. At the receiver side, right click on your Bluetooth icon in the notification area and choose “Receive a File”.
   
   
   
6. When your HTC Desire is able to connect your PC, the file transfer progress bar will be shown and once the file transfer is completed, a window will show the location of the transferred files.

That is it. Simple and easy. Have fun trying out.
