hello all. i do have a problem with php and image functions. i want to add a watermark on an image. That works, but the watermark image (png) has to be transparant. it contains a small image and the rest of the image is white. when i try to make it transparant (imagegetcolor($watermark, 255, 255, 255);) it wont get transparant. does anybody has got an idea what i am doing wrong ?
