    You're looking for something like this:

    uri = "tmp:/images/" + someidentifier
    ba = CreateObject("roByteArray")
    ba.fromBase64String(yourbase64string)
    ba.writeFile(uri)

    poster.uri = uri

    What I do for the sake of speed is write an external php script to handle the code as Roku gets bogged down real quick.
