[TYPO3] Splitting for a filename extenision

It's a Register and you can access it by using the stdWrap function data,
which is of type getText.

10 = TEXT
10.data = register:SPLIT_COUNT

But you don't need it here, since split offers you optionSplit properties.

subimage = TEXT
subimage {
    field = media
    split {
        token.char = 46
        cObjNum = |*| 1 |*| 2
        1 = TEXT
        2.current = 1
}

Will produce empty TEXT for every part except the last one which will be
"current" instead.

Not tested.
