Launch images in modal windows within Twitter Bootstrap using jQuery

So the challenge has 4 parts:
Make the image appear in thumbnail size on the page before it appears in the modal.
Change the opacity of the image on hover, so that users know if they click on it something may happen.
When the image is clicked, take information from the image tag and pass it to the modal window.
Make the image take up the whole modal window when launched.
Below is how to do it. I've highlighted the code in red.

filter: alpha(opacity=40);
}
#exampleModal > div.modal-dialog > div > div.modal-body > img
{

}
</style>

Saving and retrieving images using MySQL through PHP

I really should have looked into this a long time ago, but still. The example below deliberately doesn't use jQuery. If you want to POST files through jQuery, you'll need to use an ajax form plugin.

Right. Now we've got that out of the way, to my example. I have created a database in MySQL with a table called pictures, and I have 2 fields:
id : int(8)

picture : longblob
I have used the database class which I developed earlier to handle the requests.
At this stage, I'm just handling JPEG images.

<?php
require_once 'database.class.php';
$db = new database;
if($_POST)
{
$image=$_FILES['uploadfile']['tmp_name'];
$fp = fopen($image, 'r');
$content = fread($fp, filesize($image));
$content = addslashes($content);
fclose($fp);
$sql="insert into pictures (picture) values ('$content')";
$results = $db->query($sql);
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>File upload</title>
</head>
<body>
<form enctype="multipart/form-data" method="POST" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input type="hidden" name="MAX_FILE_SIZE" value="10000000" />
<input name="uploadfile" id="uploadfile" type="file" />
<input type="submit" value="Submit" />
</form>
<div id="results">
<?php
$arr = $db->query('SELECT * FROM pictures');
if($arr)
{
foreach($arr as $row)
{
echo $row['id'];
echo '<img src="data:image/jpeg;base64,'.base64_encode($row['picture']).'" /><br />';
}
}
?>
</div>
</body>
</html>

Enjoy!

Using lorempixum as background images

I've been finding lately that lormepixum is also pretty darn useful in providing background images.

See demo.

Using overflow hidden to better align text and images into columns

I can't take credit for this. Credit must go to Soh Tanaka for this blog post
http://www.sohtanaka.com/web-design/css-overflow-property-quick-tip/

I just tweak it a little so that it would work well within the context of this blog. Essentially it is a nice simple way of aligning text next to images without wrapping.

See demo.

<!DOCTYPE html>
<html lang=”en”>
<head>
<meta charset="UTF-8">
<title>Overflow Hidden</title>
<style type="text/css">
body
{
margin:0 auto;
width:600px;
font-family:sans-serif;
}
.thumb
{
float:left;
margin-top:20px;
margin-right:20px;
padding:5px;
border:1px solid #CCCCCC;
background:#F0F0F0;
}
.description
{
overflow:hidden;
}
</style>
