Changing image color

[lilycy]

I have learnt img_filter_colorize() of php little bit. I want to give user a option to choose color for an image. Example is hereMy code is: \[code\]<?phpheader('Content-type: image/png');$im = imagecreatefrompng('flower.png');imagefilter($im, IMG_FILTER_GRAYSCALE);imagefilter($im, IMG_FILTER_CONTRAST, 255);imagefilter($im, IMG_FILTER_NEGATE);imagefilter($im, IMG_FILTER_NEGATE);imagefilter($im, IMG_FILTER_COLORIZE, 255, 0, 0);imagepng($im, 'flower1.png');?>\[/code\]This code is creating a new image with red color but here I don't want to create an image, only display in screen.For example if user selects red button image changes to red and so on.Is this achievable?Is there any other way to do it (javascript, canvas or any other)?Please help, thanks in advance.
