Best option is applying a watermark to the photos so when taken it still shows your mark. They can be removed with effort, but people are less likely to take them. In order for a browser to show the image, it must download the image and so your image has been taken, which means if a visitor can see it, they already have it, which is why babyjenniferLB stated it's impossible to do what you want.
Actually I have seen this before. It was on a baseball website when I was looking for a new glove. I was trying to pull pictures of gloves off the site to show my dad, but every time I tried to drag it off and onto my desktop, something popped up, I don't remember what it said, but it wouldn't allow me to drag the picture to my laptop. It was very strange. But it is not IMPOSSIBLE!!
There are other methods. The simplest being to take a screen shot of the page and simply crop the image. No one can protect against that.
If someone wants the image, they will get the image.
If you enable the develop menu in webkit, you can then use the inspector to see all resources on a page, you can then download them to your heart's content. Not many people will use this method and doing a screen grab is easier, but with this method you'll at least get the original.
I wouldn't worry about it at all. I don't want this to sound negative, but it's unlikely anyone will want to steal your photos. Don't upload the full resolution, and put a small watermark in the bottom corner - solved.
What is someone going to do with a 400 x 600 resolution photo? Blow it up 10x and make print copies of it and sell them? I don't think so. Worst case scenario is someone put your images on their site. In this case your website will get free exposure (because of the watermark).

As others have said, the whole point of the web is that you put files up on a server and other people download those files to their computer in order to view them. So if they can see the photo, they've already downloaded it.
Some sites install scripts that disable right-clicking so you can't right click on the image and "Save", but that annoys people who legitimately want to right-click on the page for other reasons.
In addition to screen capturing, one can find the source filename of the image and enter the URL manually, or use Unix shell tools like curl and wget, or find the image from the browser cache. In Safari you can view the Activity window and download the image from there.
My favourite was the artist website that disabled right-clicking, but when I discovered the file name was site.com/blah/images/image.jpg, I just entered "site.com/blah/images/" into my browser and they hadn't disabled directory listing... I could pick and choose any image I wanted.
