Setting up a 'avatar' picture?

[DarrenReeder]

Hello, This is a question on how i can set up so if i have a image called 'pic.png' (for example)..how can i check the size of it (100pixels x 100pixels) for example..so i can make it so it will only display the image if its the correct size...

Also, if i made a link to a direct image cna i check the size of that..so this way i can just make it so it says 'Enter URL of your image' and it will save that url to the mysql

You can use either GD or Exif functions on an uploaded file. Exif should be better, because it requires to read the image header only, but it is not installed on some servers.

 

$data = exif_read_data('file.jpg', 'COMPUTED');
echo $data['COMPUTED.Width'];
echo $data['COMPUTED.Height'];

Take a look at getimagesize and filesize

1 exif if supported, 2 gd if supported and not jpeg or tiff, 3 getimagesize otherwise
