writing a config.php file for image directory?

[xpiamchris]

So I have succesfully uploaded images to a directory on my server... and i have the image name next to the appropriate mysql row.

What Im stuck on is... how would I have it so that I can call on the file name and have the image display?

I read somewhere to write a config.php file so that I can direct it to the right directory/location?

so for example...
$imagelocation = "/filedirectory"/
and then I can call the file name through mysql queries?

Can someone clarify or adjust this to operate the best way?
thank you!

You would grab the image name from the database and then concatenate the directory path to the front. Something like this:

$image = '/path/to/images' . $filename;

Is that what you are talking about? Not quite sure.
