如何在PHP脚本中回显图像？ [关闭]

I have a small problem. I have made a small database for storing found geocaches. When someone submits a geocache, and it successfully goes into the database, I want an image to appear. This is a snip of the code that I have right now. All it does is say, "Thank you for submitting your geocache!"

if(!$query)
    echo mysql_error();
else {
    echo "<h1>Thank you for logging your geocache!</h1>";
}

This returns fine, but if i use THIS code:

if(!$query)
    echo mysql_error();
else {
    echo "<img src="checkmark.png">";
}

This code will return a 500 server error.

So, the big question, how do I echo an image in this script?

You are using unescaped double quotes around checkmark.png which terminates the echo statement early, causing it to be invalid. Try "<img src='checkmark.png'>"; or "<img src=\"checkmark.png\">"; instead.
