Hi, I;m glad to be of some help here.
------------------------------------
The website ohhotgirl.(com)uses an unusual file naming technique so *.jpg
won't work. If you want to rip the site and get all of the images, it will
take many hours mind,

use *.************************* or longer.. for the file type.

the reason being is that the files are named such as :

*121524194216.jpg**imageform**
*12152419407.jpg**imageform**
*Daniella_Sarahyba4.jpg**imageform**
*jesse-jane-friends-picture2_1200442684.jpg**imageform**
*jesse-jane-20080925004517174.jpg**imageform**
*jesse-jane-20080925004435674.jpg**imageform**
*jesse-jane-20080925004158254.jpg**imageform**

As you can see, the file names are not what you would expect but now that you
know, you can download them. Make sure that you have a look at my other
entries that I submitted earlier on. 
All of the download instructions are included to get you started. You can
apply the same technique
to any other website that has images like this.
