Paths to your images is your issue, as far as I can tell.
Your website is under http://debojam.bugs3.com/personalgallerie/images/
Your HTML images sources are mentioned as src="thumbs/personall1.jpg"
If I navigate to http://debojam.bugs3.com/personalgal...personall1.jpg
I get a 404 Error, which means the path is incorrect, or the image is missing.
The way you wrote your code means that the 'thumbs' folder would be in the 'images' folder. If the thumbs folder is above the images folder in your structure, then you will need to use something like src="../../thumbs/personall1.jpg"
The links to the jQuery library and your other JS files looks correct to me.
