Image Convert

[Judit1983-2]

I want to convert images to jpeg, png, bmp and gif but got the following error messages:

Warning: imagecreatefromwbmp() [function.imagecreatefromwbmp]: 'uploads/017.JPG' is not a valid WBMP file in C:\xampp\htdocs\imageconvert\function.php on line 144

 

Line 144 is:  $image=imagecreatefromwbmp('uploads/'.$filename); 

 

Warning: imagepng() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\imageconvert\function.php on line 147

 

Warning: imagestring() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\imageconvert\function.php on line 148

 

Line 147 and 148 are:

 

$newimage=imagepng($image,'uploads/' . $file . '.png',9);

        imagestring($newimage,5,0,0,date("Y.m.d H:i:s"),10);

 

 

 

 

The whole code is:

It is a little late, so I will need to look at this more closely. But one thing I noticed is that you used is_dir. It will probably be better to change it to:

 

if (!file_exists('uploads')) {
     mkdir('uploads', 0755);
}
