Verifying image links

[Porl123]

Are there any functions that can verify an image link to make sure it's the right format? Thanks in advance

When you say format im guessing that you mean checking the file type i.e. jpg, gif

 

For this:

// image.jpg would display jpg
$fileType = substr($filename,strpos($filename, ".")+1);
print $fileType;

 

You may also want to check if the file exists

if(file_exists($pathToFile)) {
// ok file exists
}
