[TYPO3] getting width of new gifbuilder image for wrap?

[R. Germershausen]

hello. is there any way to get the width of fresh generated gifbuilder 
image to set the width of a span dynamically?

25 = LOAD_REGISTER
		 25.meinbild.cObject = IMG_RESOURCE
		  25.meinbild.cObject.file = GIFBUILDER
		  25.meinbild.cObject.file{
			  backColor = #FFFFFF
			  XY = [10.w]+20, 18
			  transparentBackground = 1
			  10 = TEXT
			  10.text.field = nav_title // title
			  10.fontFile = fileadmin/template/fonts/VistaSanReg.ttf
			  10.fontColor = #696767
			  10.fontSize = 12
			  10.offset = 1,8
			  10.niceText = 1
			  10.niceText.sharpen = 10
			  20 = TEXT
			  20.text.field = nav_title // title
			  20.fontFile = fileadmin/template/fonts/VistaSanReg.ttf
			  20.fontSize = 12
			  20.niceText = 1
			  20.niceText.sharpen = 10
			  20.offset = 1,17
			  20.fontColor = #00A0C6
			   30 = IMAGE
			  30.file = 
fileadmin/template_visionate/images/arrow/main_arrow_double.gif
			  #10.file.width = 759
			  30.offset = [10.w]+10, -1
			
     	   }
		   25.meinbild.cObject.stdWrap= LOAD_REGISTER
		   25.meinbild.cObject.stdWrap.typolink {
             parameter.field = uid
			
             wrap = <span style="background-image: url(|);" 
class="menubg_lev2"></span>

			ATagBeforeWrap = 1
             ATagParams.cObject = COA
             ATagParams.cObject {
               30 = TEXT
               30.dataWrap = id="act{field:uid}"
		
               40 = |*| 0 |*| TEXT
               40.value = class="last"
             }
           }

at wrap = <span style="background-image: url(|);" 
class="menubg_lev2"></span> i would like to set the width of the image 
as inline style.

nice weekend to all.. ;-)
