[TYPO3-english] Create GIFBULDER image object using the API

[Matias Coca]

Hi!
I want to create a gifbuilder object image with an additional gifbuilder
image object inside using the api, I have read the api but i can't find the
proper way to do this.
I was able to create the main gifbuilder image but can't put the additional
image inside.

Below is the code witch i was trying

  .......
  .......

  $path = $myImagePath;
  $cObj = t3lib_div::makeInstance('tslib_cObj');

  $imgTSConfigThumb['file'] = 'GIFBUILDER';
  $imgTSConfigThumb['file.']['XY'] = 150,100
  $imgTSConfigThumb['file.']['format'] = 'jpg';
  $imgTSConfigThumb['file.']['quality'] = 85;
  $imgTSConfigThumb['file.']['backColor'] = 'white';
  $imgTSConfigThumb['file.']['10'] = 'IMAGE';
  $imgTSConfigThumb['file.']['10.']['file.']['import'] = $path;
  $imgTSConfigThumb['file.']['10.']['file.']['maxW'] = 150;
  $imgTSConfigThumb['file.']['10.']['file.']['maxH'] = 100;
  $imgTSConfigThumb['file.']['10.']['align'] = 'c,c';

  $thumbpath = $this->cObj->IMG_RESOURCE($imgTSConfigThumb);
  $link = '<img src="'.$thumbpath.'" class="thumbnail" />';

  ........
  ........

I suspect that the additional image object need to be process before hand,
can't find the proper function in the api doc.
Any hints or example will be great appreciated.

Thanks.
