i want some suggestions.
i have to do customize image banner means i have to customize text on images.
for example there is a text on image. this text can customize.after submit this background image and text total convert into one image
Have a look at imagefttext/imagettftext and imagecreatefrompng/imagecreatefromjpeg (or the corresponding function you need).
To create an image from a text, you can use the imagemagick library http://www.imagemagick.org/script/convert.php
