Thanks!

Any chance of having that code on multiple lines? :)Anyway, for the first question, you can rename the file when you move it, on the move_uploaded_file($temp,"galeria/" . $name); line. You can apply the resize() function to the file after you move it.

Resize? the first question, its not resize, rename it with md5

[Synook]

Yeah, the first bit of the sentence was the answer to your first question, and the part after the comma was in reply to the second. :)For example, you could write the line as such:

move_uploaded_file($temp,"galeria/" . md5($name));

Its not working i know, because i try it yesterday.ups my failure im modifying a wrong file :)Ok its encrypted, but i have an another problem, the file lose the file type name, idea?

You could get the type or extension (.jpg, .gif, etc) before you encode the name. Then add the extension after it's encoded. Something like:$ext = // get the extension$name = md5($name) . $ext;

done $ext=substr($name, strrpos($name, '.'));Only the second problem have, i want to thumbnail the image fileSomebody help me!

[jeffman]

The GD library can help you with that: http://www.php.net/manual/en/book.image.php . Building thumbnails on upload is the most efficient use of time, but building them on the fly is not unheard of.In any case, the result is vastly superior to "resizing" the image by altering the width/height attributes in your page.
