Question: I have a weird problem with images in visual web developer, 

I cant change my images properties from properties panel (my changes don't take effect) and all images in my website have gotten the same size 

when I resize one image (by dragging the border), all images get that new size?

any idea?

Answer: 
Qualify it with the `>` descendant selector:

```
$("table.Table22 > tbody > tr > td:nth-child(even)").css("background","blue");

```

You need the `tbody` qualifier too, as browsers automatically insert a `tbody` **whether you have it in your markup or not**.

*Edit*: woops. Thanks Annan.

*Edit 2*: stressed tbody.
Untested but perhaps: <http://docs.jquery.com/Traversing/not#expr>

```
$("table.Table22 tr td:nth-child(even)").not("table.Table22 tr td table").css("background","blue");

```
