Create a separate PHP file that creates your image, and put it in the
HTML like this:



All file.php should do is output image headers and the binary image
data.

Re: [PHP] IMAGE CREATE() header problem

[Dani]

Thanks for the advice.
I found out there I shouldn't put the script in between any html tags at all.

Now my question is:

What if we want to insert image which is generated by the php in the table?

thanks

Double check your file for the whitspace like the others have stated.
I tried your example and had no problems with it...

Thanks Miguel!

I have checked everything but it seems there aren't any blank space but I
still get the error message.

RE: [PHP] IMAGE CREATE() header problem

[John Holmes]

Something is being output in index.php on Line 10. That's causing the
