Uploading & Retrieving Images From Database

[MoFish]

Hey Everyone

I have been working on adding a retreiving images from a database, and stumbled accross this method using BLOB which I am currently trying to implement into my website.

I have the following upload code, to add the image to my SQL database, but am having problems displaying the images, and am not sure if this is the best way to do things.

Here is my database structure with a couple images in it

1) Is this the best way to store the images, or should I simply be storing the URL in a varchar instead and calling that to the page? If so how can I code it so when the user uploads a file it adds that path to the database? That confused me.

2) If this is the best method to do it, how on earth do I display an image using this method? I have tryed and tryed but have come no where near close to displaying anything like an image.

Any help would be greatly appreciated.

Thanks again - Mofish!

        $fp = fopen($tmpName, 'r');
        $content = fread($fp, $fileSize);
        $content = addslashes($content);
