[TYPO3-english] Check if there is an image in the ressources of a page

[Cédric Aellen]

Here's the solution

```
lib.menu = HMENU
lib.menu {
    special = directory
    special.value = {$lib.sysfolder}
    wrap = <ul>|</ul>
    1 = TMENU
    1 {
        NO {
            allWrap  = <li>|</li>
            ATagTitle.field = subtitle // title

            before.cObject = COA
            before.cObject.stdWrap.if.isTrue.field = media

            before.cObject = IMAGE
            before.cObject.file.import = uploads/media/
            before.cObject.file.import.field = media
            before.cObject.file.import.listNum = 0
            before.cObject.altText.field = abstract
            before.cObject.stdWrap.typolink.parameter.field = uid
        }
        ACT = 0
    }
}
```
