Ok, give bitpim a shot. It's a program which allows you to transfer media back and forth between CDMA
phones to and from your computer.
You can find the download here: http://www.bitpim.org/#download
If you don't see UX5500 available, try VX5500. If that doesn't work for you, then you may have better luck with VX9200.
As a last alternative (since Win7 is largely unsupported for that older model phone), is to simply send yourself the images via email. Simply compose a picture message, and then put your email address in the "TO:" area and send it to your email--sure you can only do it one at a time, but it beats having no pictures.
