How can I get photos from a phone camera onto my computer.?

If the battery charging socket is a mini-USB port it may have a dual function (mine has). If so, you need the right connector to link it to your computer. Otherwise find a friend with a more modern phone, send the photos to them, and ask them to forward them to your email address.

Tell us the model and we may have some more ideas. If it doesn't have a USB port, it probably has a removable memory card. These things all had some method of printing photos and if it will speak to a printer, it will speak to your computer.

Need to know the type and model of phone to answer in full. some older phones use built in communications devices and/or memory cards if your phone has a memory card you can use this to transfer information to your computer threw a card reader or other interface device.
