[Typo3] Typo3 Rendering Problem

[Stefan Dreyer]

Hello,

i have typo3 page with subtitle / title created by the gifbuilder.
On one page i have an extension installed, which should change the
subtitle-image.
I try to set $GLOBALS["TSFE"]->page["subtitle"] but the image
is rendered before the plugin is rendered. Is there a way to
render the image after the plugin?

Example Template:

seite.5 < plugin.tx_changetitle_pi1

temp.header_image_gifbuilder = IMAGE
temp.header_image_gifbuilder.file = GIFBUILDER
temp.header_image_gifbuilder.file {
    XY = [20.w]+10, [20.h]+40
    reduceColors= 32
    backColor = #99ccff
    20 = TEXT
    20.text.field = subtitle // title
    20.backgroundColor = #99ccff
}
seite.10.marks.HEADERIMAGE < temp.header_image_gifbuilder
