Is your phone a V3 or a V3i? I assume it's a V3 since it doesn't take a memory card. The V3i does take a micro SD card. According to the manual for either, you should have no problems sending pictures to another device via bluetooth.
In case you don't have a manual, here's the procedure to send a picture, etc. to a device you have paired with the V3.
Sending a Picture, Sound, or Video:
Highlight the object on your phone that you want to send to
the other device, then press Menu > Copy.
Select a recognized device name listed in the Object Exchange
menu, or [Look For Devices] to search for the device to which
you want to send the object.
