TYPO3 File Abstraction Layer FILES listNum - typo3

Question

I have a menu and want to access on media files from the page configurations. This works quite well, but it gives all the images of the media files. ListNum it does not work. Do you have an idea or an alternative solution? Important I want to use file:current:description and file:current:title
after.cObject = FILES
after.cObject {
references {
table = pages
fieldName = media
# listNum = 1 not working
}
renderObj = IMAGE
renderObj {
file.import.data = file:current:originalUid
file.width = 250
file.import.listNum = 1
altText.data = file:current:description
}
}

Answer 1

The code of the OP and of maholtz's answer does not work in current TYPO3 versions any more. Here is the correct TypoScript for 6.2 and beyond:
1 = TMENU
1 {
wrap = <ul>|</ul>
NO = 1
NO {
wrapItemAndSub = <li>|</li>
stdWrap.override.cObject = FILES
stdWrap.override.cObject {
references {
table = pages
fieldName = media
}
renderObj = IMAGE
renderObj {
file.import.data = file:current:uid
file.treatIdAsReference = 1
titleText.data = file:current:title // field:nav_title // field:title
altText.data = file:current:alternative // field:nav_title // field:title
}
# start with second image
begin = 1
# show only one image
maxItems = 1
}
}
}
The parameter begin defines which of multiple images should be used (e.g. if you need one image as a headline background for the page and another one as an icon in the menus).
If you increase the maxItems parameter, multiple images will be returned (if multiple images are defined in the resources tab).
If you want to append/prepend the image to the menu text instead of replacing it, you have to change stdWrap.override.cObject to after.cObject or before.cObject in the above code.

Answer 2

after.cObject = FILES
after.cObject {
references {
table = pages
fieldName = media
# listNum = 1 not working
}
renderObj = IMAGE
renderObj {
file.import.data = file:current:originalUid
file.width = 250
file.import.listNum = 1
altText.data = file:current:description
}
# start with first image
begin = 0
# show only two images
maxItems = 2
}
There are two registered filled:
REGISTER:FILES_COUNT
and
REGISTER:FILE_NUM_CURRENT

Here comes another example with stacked image references. This code can be used with jquerypicture.
lib.headerImg = COA
lib.headerImg.wrap = <picture alt="some alttext">|</picture>
lib.headerImg {
// <source>
10 = FILES
10 {
references {
table = pages
uid.data = tsfe:id
fieldName = media
}
renderObj = IMG_RESOURCE
renderObj {
file.import.data = file:current:uid
file.treatIdAsReference = 1
stdWrap.dataWrap = <source src="|">
# the 2nd pic gets another attribute
stdWrap.dataWrap.override = <source src="|" media="(min-width:600px)">
stdWrap.dataWrap.override.if.value = 1
stdWrap.dataWrap.override.if.equals.data = register:FILE_NUM_CURRENT
# altText.data = file:current:title
}
begin = 0
maxItems = 2
}
// <noscript>
20 < .10
20.begin = 1
20.maxItems = 1
20.renderObj.stdWrap.dataWrap = <noscript><img src="|" alt="{file:current:title}"></noscript>
}
