Image shown like text :? :(

[rubio]

Like i announced it before, I´m using two joined classes in my apli. First of then cath a column of a mysql table, and the second show their values in a line chart image. This second one works fine alone, but i get this result in my browser when i use it with the first one:
Warning: Cannot add header information - headers already sent by (output started at c:\apache\htdocs\test\test.php:7) in c:\apache\htdocs\test\Linechart.php on line 30
ÿØÿàJFIFÿþ:CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 0 ÿÛCÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ
ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÛC

The image is not displayed, but it's shown like text. 😕

Now, i´ve discovered, i can make a .jpeg file correctly, but still getting than my apli don´t show any header warning, the image is shown in text code.
Can anybody help me please??? 🙁
Thanks.

If you're using the script to print the image, you may want to try sending the image/jpeg header like this:

<? 
header("Content-type: image/jpeg"); 
imagejpeg($im); 
imageDestroy($im); 
?>

make sure you're not printing/echoing anything above this. So to view the image, you would just call your script in the browser.

And if you want to print out the image using html like <img src="blah.jpg">, use something like this:

<? 
Header("Content-type: image/jpeg"); 
ImageJPEG($im, 'filename.jpg');
ImageJPEG($im,'',20); 
ImageDestroy($im); 

echo "<img src=\"filename.jpg\">";
?>
