Count elements in jQuery
2010/05/02 | Permalink | Comment?
The method you can use to count the element’s of a jQuery selection is “size()”
```
$("div.class").size();
```
So you are able to do
```
if ($("div.class").size() > 0)
  // Do something
else
  // Another thing
```
or whatever you want to do

PHP image resizing
| Permalink | Comment?
SmartImage is a free PHP class under LGPL licence.

With SmartImage you can easily:
- resize images (in order to do thumbnails)
- add a watermark to your images
- convert files from/to jpg, gif and png formats
- optimize jpg size and quality
- rotate
It is really simple to use, for instance you can resize and image with 4 lines of code:
```
include "SmartImage.class.php";

$img = new SmartImage($src);
$img->resize(120, 80);
$img->saveImage("newimages/new07.jpg", 90);
```
