The vx8300 can use a microsd memory card. Based on some discussions I found through google, it appears the initial firmware supported up to a 1gb microsd card and, starting with firmware version 3, a 2gb microsd card. I didn't spend enough time searching to see if firmware updates supported any higher capacity microsd cards like 4gb. And I don't know if it's still possible to take your phone to any place that is still capable of upgrading the phone's software.
I don't know if it's possible to still find a microsd memory card of that size at a store.
However, the good news is that small capacity microsd cards are still available on ebay. I think the smaller capacities are 512mb, 1gb, and 2gb. For the smaller capacities, our Sandisk cards continue to be reliable.
There's a chance the phone might still partially be compatible with a larger capacity microsd memory card because I've read that a phone will be able to "see" a certain amount of that capacity. So, if a phone's software was written to accept up to a 2 gb card and an 8gb card is inserted, then the phone will be able to use up to 2gb of that card. This is the experience that some have reported for some phones. I don't know if there are exceptions to this experience. Hopefully someone you know has a large capacity memory card you can borrow so that, if your vx8300 can't "see" any of it, then you haven't made a purchase that's of no use to you.
So, with a memory card inserted into the vx8300, transfer the photos onto it and then use a memory card reader that you'll plug into your PC to read the memory card. If you need further information on transferring pictures from the phone to the memory card, here's a link to the phone manual:
