So you can change the colour of an image through php, but I don't know exactly how to apply the chosen colour to the image

I do not understand what you mean. :S

Ah, so you would like to create dynamic images via PHP? Google for "Dynamic PHP images tutorial" and that should get you some results worth reading.
Jacob.
Jacob.
thank you 
most of the time GD dont work in anything outside of IE browser
lmfao what are you talking about noxus. GD is ran through php which is all server side. It doesn't matter what browser you use.
Either think before you post or explain better what your saying. Because as it is you're making yourself look pretty dumb.

Jacob.
alot of sites with authorization login/registration pics for input fields. remove them if you go back to the site in opera or firefox. you`ll just have a blank page saying image cannot be displayed. image has errors or image is empty
Sounds like you've got the Content-Type header wrong, or some such, there is no reason that correctly written GD will error in browsers other than IE. If that does happen, you're doing it wrong - not GD.
nope. its just the browsers. search for "content type png" and theres loads of places saying they dont work, if you want it working. just miss out the header(content-type...) all together
Show me an example of it not working, code included please.

That is a user error. That's like trying to drive a car with no steering wheel.
its just all the cheap browsers. you can create modified images using GD. for authorization codes etc.. as soon as you add header(content-type); like your suppose to do. the page wont load outside of IE. without the header(); line. the page will work as it should in all browsers

omg it works!
mine works. unless i have header(content-type) then all the lame browsers like firefox extra will just return a page with some guff about a blank or errored image. just like many. on any search engine. its nothing to do with lame code. its the lame browsers. just like they cant handle css properly
Another post, still no example with code. And with proof to the contrary in trippin's post above.
What we have here is a troll. Ignore him.

You could make the code much shorter than that, simply by using arrays and array keys. e.g
could be written as:
I haven't run this, as it's 1am, so there might be a few errors, but you get the general idea. This is much shorter code, and much quicker to run. There's quite a few savings like this to made.

Thats all well and awesome swordz but the guy isn't trying to make a calendar, he was asking about modifying a .png image, and then noxus throws in random code for a calendar.
I can't say much because the rest of us got off topic talking about whether GD works or not with the header information supplied (which is does contrary to what noxus says)... but still.

i originally said that GD`s createimage....() function wont work outside of IE. because most other browser will give you a error message if you have the header(content-type) in the <head></head> like your suppose do.
mine only works in other browsers like firefox etc. if i dont use header(content-type); http://c0re.vndv.com/login.php?op=register
the problem happens to many people if you do a search. so its not lame code. its just the browsers
with the calandar code. giving you the calandar block at the top left

"if you have the header(content-type) in the <head></head> like your suppose do"
uhh... what? header() must be called before ANY output, and there is likely to be no need to call header if there even was a <head> because the assumed content-type is text/html. You seem to be very confused - if I were you I'd re-read what the PHP manual has to say about GD.

either way. in some browser GDs create image dont work
Still untrue. You obviously need to do as alex says. Unless you can actually provide proof other than saying to Google it, then i'll assume you don't have a clue as to what your talking about.
