Question

Automatically generate <img> and then insert it into a <html> page after uploading the im into an FTP folder?!

Answer 1

A:

Check out the function opendir in php :

http://us.php.net/opendir

You can just have a php page that does opendir on your ftp directory, then spits out an img tag for each .jpg file in the directory. This can read teh directory each time you open the page.

Answer 2

+1 A:

As I understand you correctly, you just want to have a page showing every image in a specific folder. That can easily be done with the glob() function:

foreach(glob('folder_with_images/*.jpg') as $image){
  echo '<img src="'.$image.'" alt="" />';
}

That's all. Just set up the "query" for the globas you need it. You don't need to do any kind of cronjob or update. It simply show all available images "live" as you open the page. I use glob() and not opendir() because you can use filter like "*.jpg" which you can't do with opendir().

When you have multiple file types, you can use scandir() and a if-statement:

foreach (scandir('folder_with_images/') as $image) { 
    if(substr($image, -3) == 'jpg' || substr($image, -3) == 'gif' || substr($image, -3) == 'png'){
        echo '<img src="'.$image.'" alt="" />';
    }
}
