    <p>In my site I will let users upload product images and each product image will have different versions of varying sizes. How do you suggest I keep track of all these images so I can easily deal with insertions and deletions?</p> <p>The system that I have coded at the moment basically records image data (paths, sizes, date, etc) in a DB row on upload. Images file names are generated by </p> <pre><code>md5( microtime() ) . $this-&gt;auth-&gt;user_id; // 55bedba35a57c710e73fee21106006b71 </code></pre> <p>and paths like this:</p> <pre><code>'./img/'.substr($file_name,0,1).'/'.substr($file_name,1,1).'/'.substr($file_name,2,1); // /img/5/5/b </code></pre> <p>so its</p> <pre><code>// /img/5/5/b/55bedba35a57c710e73fee21106006b71.jpg </code></pre> <p>That is for each "image" (the original image). I'm still not sure how to go about recording the versions.</p> <p>The thing is I'm a bit paranoid about integrity so the thought of somehow images getting deleted but still having records or having images with no record bothers me.</p> <p>Is there anything (library or something) that can help me connect the DB - Filesystem gap?</p> <p>I'm working with CodeIgniter if that is of any help</p> <p>Thanks in advance. Please let me know if I didn't make any sense, heh.</p> <p><strong>EDIT</strong></p> <p>I'm thinking of storing the original as a blob in the database then generating variations and placing them all in the same folder. This way I think it might be easier to regenerate all images in case of missing images and delete the folder to delete all files when necessary. This would probably make my DB size unbearable no? What do you think?</p>

    1. CODepending on how big the images are, you could maybe store them directly in the database as a blob.. ? that way you only have one central point of storage. You db could get big fast though

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
