How to create a unique image file for each unique user and display the image via html.
I am trying to write a couple of lines in php that I'm going to insert into the "activate" function of a registration.php. The goal is that upon account activation a predefined image will be written into a predefined directory. The image name must be unipqe for each user. I was thinking along the lines of this:
$im = blanktemplate.png
$filename = "images/users/$user_id"
imagejpeg($im, $filename, 100);
Is this a good method? Am I thinking along the right lines here?
Then I want to display that image in an html page. Something like <img src={"$user_id".jpg}/> I want the image that's being displayed to be determined by the user that's logged in at the time.
$im = blanktemplate.png
$filename = "images/users/$user_id"
imagejpeg($im, $filename, 100);

Would the md5 hash prevent them from linking to the image outside of the site?
Ok, I can create an image with the following:
$user_id = 1234; //instanciated for testing
$im = imagecreatefromjpeg("image
$filename = "images/users/$user_id.jpg
imagejpeg($im, $filename, 100);
But I can't seem to view the file using a variable.
<img src=images/users/{$user_id

Ok I think you're code is good. I just need to somehow instanciate the variable user_id. I'm going to create a new question.
You could also do it like
$filename = "images/users/".md5($user_
and then
<img src={md5($user_id."xx1.jpg
which you would do when you don' want a user to be able to see other users images (just by changing the number.
The xx1 could be any string that you want (just keep them both the same).
