On the topic of copy protecting images...
One approach often taken is to disable right clicking on the site. Several people do this but I'd advise against it. I think it makes the sites appear tacky somehow, but more than that it's an annoyance that removes some legitimate functionality and it is completely trivial to get the pictures anyway.
So don't do that.
Another option is to have the pictures as part of a flash slideshow.
As far as the site visitor's browser and computer are concerned the slideshow is a single image and the shots can't just be saved individually.
However that would mean a rather large overhaul of some of the site and can be worked around using the Print Screen button that comes free with every keyboard and about 30 seconds in MS Paint or some other image software.
One that MIGHT work is to use mouse-overs. Have an unwatermarked image which is replaced with a watermarked one whenever someone puts their mouse pointer over the image.
It would mean the website took longer to load though, and that's not a good thing.
Another one that might be possible (not sure if it is, but it's a thought and one for web developers, not me) is to cover each image with a second, completely transparent image. That way if the user clicked and dragged, right clicked or anything else they wouldn't get anything more than a blank (well, transparent) image. That still wouldn't stop screen-shotting though.
The brutal reality is that if you don't want your pictures (of anything, family, work, general photography, fine art - anything) using without your knowledge (let alone your permission) for everything from dishonest means, through personal websites all the way to commercial adverts and news publications - DON'T put it online.
There really isn't a foolproof way to stop people using the images for reasons you don't know about.
I've even seen an example of someone taking a high quality, watermarked image (this was some digital artwork, and very good at that) - spent time and effort to remove the watermark and restore the image to full glory - and then claimed it as their own.
So, the above are your options, all have their drawbacks and all (including watermarking) can be worked around, from the simple action of dragging to the desktop, to screenshots, to time in Photoshop or GIMP.
Finally, some nice work on the website. I agree with slemishwoodcrafts though, I don't see a cable on the 4 legged lamp. If you go to image 4 in that gallery there's a good shot of the lamp put the flex is nowhere to be seen! How have you managed that?
