I agree, it's amazing the amount of untapped talent out there.
I came across a lot of these, mainly on Ebay, when I was looking for a woodburner several years ago.
The pictures have nothing to do with me, I just collected them. The photos belong to the creators of each piece. As they are either making these pieces commercially or are just proud of their work, they allow others to post the photos elsewhere. If I post one in error, the copy write owner can make me take it down & I'll probably get a wrap on the knuckles from the forum mods.
Saving photos is easy once you know how. The quick & easy way, as built into Windows, is to right click on the image & select 'Save Image As' from the pop up menu. In the window that opens you can then choose a title for the image & select where you wish it to be saved.
