I was sure that the images were being stored and called from the images

I
solved it by inserting the path in the call from the DB. I am wondering
now
if they are stored in both locations.

Gary:
Both locations? I think you are confusing yourself.You either have the
images stored in the database OR the file system, but not both.
However, I think you have the images stored as files within the file
directory, such as:
http://yourdomain.com/images/picture1.jpg
Now, in your database you should have only the path name stored (i.e.,
images/picture1.jpg) and not the image. However, I usually only store the
file names and NOT the path. That way I can move the images to where ever
I want and only change their reference in the HTML.
To recap, to show any image you use the HTML img tag, such as:
<img src="images/picture1.jpg">
To tie this statement to a database, you need to pull out the image name
(or file path) from the database and use that. Something like this:
$query = "SELECT file_name FROM pictures WHERE id = '$id' ";
$result = mysql_query($query) or die();
$row = mysql_fetch_array($result);
$file_name = $row['file_name'];
And then in the HTML you would use:
<img src="images/<?php echo($file_name);?>">
If you can get to this part, then we can deal with placing a watermark on
the image before showing it.
Please let me know when you get this part to work.

PS: There is no need to use a LONG BLOB in your database -- that's just a
waste of space.

Thank you for your reply.
I have the images being displayed in the browser fine, my issue was that I
was not able to get the watermark to show up. I believe the issue was here
$img=imagecreatefromjpeg($_GET['pic']);
in that 'pic' is asking for the image that I wanted the watermark displayed
on, and what I put in did not work. Since the image file name is being
stored in the DB, I tried
$row_WADAimages["image_file"]
as well as a few others.
What do you suggest I changed "longblob" to, and is it safe to do so?
Again, thank you for your help.

gary:
At some point you're going to have to learn:
1. The difference between a VARCHR and a LONGBLOB. Question: If you
are simply storing the name of an image file, then why use a LONGBLOB
to do that? Please look up the difference between the two and post
your findings here;
2. The GET (again) is *not* the way to get the name of the image. I
have shown you how to pull the name of the image via a database call
-- so why do you go back to your old code telling me what the problem
is? If you already know what the problem is, then why ask me?
3. If you want my help, then use what I have shown you instead of
going back to your past problematic solution.
It looks to me as if you are not willing to learn but rather are
looking for a simple solution. I am not going to write your code for
you.
Now, please use my last email and write code to present an image as I
demonstrated to you. When you can do that, then we can address how to
put a watermark on the image. However, if you fail to do that and
continue to bring up old nonsensical code, then I will discontinue
commenting re this thread.
Cheers,
tedd
