Photo Galleries are back! Instructions below.

Dear forum users,
Thank you for your patience with the Photo galleries. We've got your galleries online!
We have finished writing a custom script to migrate the PhotoPlog to vBulletin5’s albums.

Unfortunately V-Bulletin killed the "Photoplogs" in their software upgrade which was unforeseen and we're the first development group to have written a script for getting the galleries back... that said, it took some time to reverse engineer the code and get the albums to move over seamlessly!

Forum users will be able to access their “PhotoPlog” images through their user profile page by clicking on the “Media” tab.
They will also be able to browse other albums by going to the albums page. (On the forum site, there is a link in the black bar beside “Forums” to the albums.)

In order for users to create an album please follow the steps below.
1) Go to user profile page and click “Media”
2) Click Add Photos
3) Enter Photo Gallery Title in the first field
4) Click Upload or Select from Photo Album to add photos
5) Click Post
6) Once posted, the album will be created as a “Topic” on the albums page for the public to see. The topic title will be the “Photo Gallery Title” they created before uploading their photos.


To create this migration path we used vBulletin5’s default album structure. Unfortunately, it won’t work like the “PhotoPlog” but is an album/gallery component on the forum now.

  • Engineering Bricks??

    Hi all from Sunny Worcester, England

    The pictures in photo gallery have all been really inspirational so a big thank you to everyone in this community for sharing what you've done.

    I have begun building a scaled down version of the Pompeii oven. I am now trying to source an alternative to fire bricks as they are SO EXPENSIVE!

    Would anyone out there know if the Blue Engineering Bricks that are readily available in the UK are suitable substitute, or even red building bricks with holes in?

    Many thanks , Mark

    Have a look at the Tom Jaine book about building ovens - I think he talks about using engineering brick for the dome, but firebrick for the hearth. Never treid it, so can't comment, but engineering bricks are very tough, and very dense, so might be OK. Would suggest not using the perforated bricks - much lighter and in my experience, easy to crack.

      When I do a google search for "engineering bricks" most of the pictures look like ordinary house bricks with holes. Here's one that's specifically blue:

        Thanks for the reply Carl, i'll certainly look at the book. My neighbour seems to think they'll be fine, as you you said, they are very dense and rock solid, just heavier than fire bricks but a fraction of the cost.

          Hi thanks for taking time out to help. I have attached a picture with the brick I hope to use below. Have had to scale it down in order to attach it so hopefully its clear enough to tell.

            There have been builders in Australia who have used what they called engineering bricks for their ovens, with apparent success, but the word seems to cover so many things that it might be comparing apples and oranges.

            Ovens were made with stone and terracotta tile for millenniums before the invention of alumina based refractories. Just remember to insulate, even in curing, to prevent big temperature variations from outside to inside.

              I was going to use engineering bricks before I found some cheap firebricks on ebay. If you're buying new bricks, you have a choice of class A or B, with class A's absorbing less water than B's. Class A's are stronger, and more frostproof than B's (the class relates to both the strength and water absorption - see engineering brick: Information and Much More from Answers.com), and are usually denser too. If you're buying used bricks - who knows. The blue bricks are probably Staffordshire Blues - I think they're class A's if I remember correctly.

                Thanks Carl.

                I've been looking on ebay, have been to numerous reclaimage yards etc, and had no joy finding cheap or used fire bricks. As its my first attempt/build I've decided I am going to go ahead with the class A engineering brick. I'll keep people posted as to whether it works or not as its certainly works out a lot cheaper!

                  If its 9lb, its approx 4kg which is the same as a super-duty firebrick [ 45% alumina ] so it should be fine. Heat retention will be great, may use a little bit more wood on initial heat up. Go for it.
