Displaying Images

[blckspder]

Hello,
I am trying to display an image for a form. I do not want to use a database and Ive been trying echo to display the image but nothing is working. Is there a library that needs to be enabled to have images displayed? I have the GD Library already enabled. Please let me know how I can get an image to display, Thank you

Depends on what you're doing. Are you trying to create a dynamic image, or just output an image binary data string through PHP?

Normally, if you read the image, you just need to set the header content-type properly:

header('Content-Type: image/jpg');
// OR
header('Content-Type: image/gif');
// OR
header('Content-Type: image/png');
// OR
header('Content-Type: image/wbmp');

That help you out?

I am just trying to read an image in the same folder as the script and dispalying it in the error message.

I already had a header content type set for text/html is this something different?

I set it this way because an email is sent if there is no error, can I set another header content type or will the 2 conflict?

Thanks for your help I really appreciate it.

the two will conflict. Let me ask you this:

1. Why are you reading the image and displaying through PHP?

2. Can't you just use the <img> tag?

Ive tried that and it wont work. The error message is displayed through the external PHP processing script. so if the user doesnt enter the correct number for the form validation they get an error message. I want to post a warning sign to get their attention. Here is the block of code

if (isset($_POST['txtNumber'])) {
$number = $_POST['txtNumber'];

	if (md5($number) == $_SESSION['image_random_value']) {
	//Mail the form
	mail($sendto,$subject,$body,$headers);
	header("location:http://www.sono-tek.com");
	exit;	
	} else {
		echo "<table bgcolor=#CCCCCC border=1 bordercolor=#000000 align=center width=45%>
		<tr>
			<td align=center><font color=#FF0000 size=+1>ERROR:</font></td>
		</tr>	
		<tr>
			<td align=center>The validation number you entered is incorrect, please use the back button on the browswer window to go back and enter the correct number, thank you.</td>
		</tr>
		</table>";
			}
}

I want the image to display next the ERROR in the else statement.

    exit;    
    } else {
        echo "<table bgcolor=#CCCCCC border=1 bordercolor=#000000 align=center width=45%>
        <tr>
            <td align=center><font color=#FF0000 size=+1>ERROR:</font>
            <img src='path/to/error/image.gif' alt='Error Image'></td>
        </tr>    
        <tr>
            <td align=center>The validation number you entered is incorrect, please use the back button on the browswer window to go back and enter the correct number, thank you.</td>
        </tr>
        </table>";
            }
}
