Use imageSaveAlpha($image, true); to preserve transparency.

Didn't see this documented, although it's outlined in imagefilledrectangle, it wasn't quite so obvious to me at first

imageSetTile($image,$imageBack);
imagefill($image,0,0,IMG_COLOR_TILED);

Will fill an image with a texture (this is great as I'm building a logo/template creator)

This function, cannot deal with transparencies.
So you need to use imagecolorallocate instead of imagecolorallocatealpha.
Thus, be careful with color variables that allready set with imageallocatecoloralpha because this can slow-down or hang-up your system.

For new images, you must allocate a color before this function will work.

Actually, it can handle pre-transparent images. To remove it you need to do something like:
   imagecolortransparent($img, 0);
to null out the previous transparency colors. ;)

This function does not seem to work with images already been transparent. If you fill at x=0, y=0, and there are still transparent parts that you did
not reach with your fill, they change to a different color.

The ImageColorSet function seems to be the solution, but i can't work with transparancy.
