PHP Drawing: "Image error, unable to display"

This PHP code is my local file 1.php, and then output the layer in Firefox, displaying "image error, unable to display." I thought it was the other day. Due to a cookie for other programming settings, I found the cookie was deleted, but the same error was displayed. Then I copied the code to the same directory. 2.php, you can display the layer on firebox. Ask the great God for advice, what is the reason.

 !--? Phpheader ("Content-type:image/jpeg");//Create Layer $img= Imagecreate (100,100);//Set Background color $bg=imagecolorallocate ($img, 0,0,0);//Output Image imagejpeg ($img);//Close Resource Imagedestroy ($img) ;

With file naming okay, press F5 refresh try

1 comments written on the code is really a tortured goblin. The

2 header is clearly written. If I had enough prestige, I would go for that downward arrow.

3 involves the modification of the picture, generally with c-f5 forced to refresh.

FileName is also relevant! always feel wrong ...

Same as 2 floor, if I have enough prestige, I'm going to go to touch which ↓ arrow
