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.

    STOP RIGHT NOW --- WHAT YOU ARE CONSIDERING IS DANGEROUS.

    Your hearth cannot be concrete it must be firebrick or similar. And if you are interested in not laying waste to significant forestland and taking tons of time to heat your oven the area under the entire oven should be well insulated. In addition the areas over and around the oven should also be well insulated.

    A 4 inch with rebar structural layer is sufficient, but used as an oven floor it will potentially decompose and in an explosive manner. Quikcrete is fine for the structural layer but not in direct contact with the heat of the oven.

    If you are going to use vermicrete for your insulating layer do not use quikcrete use Portland cement - no sand or gravel just pure cement powder and water with vermiculite or perlite.

    Even if it does not explode it will self distruct due to the heat in very short order.

    Download the oven plans from this site and read other posts regarding insulation. You will be glad you did.

      I think he means a structural slab.


      Most of the ones I have done are 3.5". It only supports the weight of the oven, so a 4" reinforced slab is fine.

      Bagged mix works too....just don't buy any that have been stored outside unless they are covered well.

        Chip,
        I misread it too the first time I read it. I think that he meant that he is not going to use a v/pcrete layer but is going to use "ceramic fiber board" for the insulation layer.
        GIANLUCA,
        A full four inches of concrete should be good to support your oven. I like the bag mix.

          Gulf, I hope that is true, but I thought I better be on the safe side, we both have read horror stories about bad designs. And his wording left me concerned. Sometimes people mean ceramic backer board ie cement board, wonder board, hardy backer..... And that would be a disaster.

            To be clear sorry!! This is the structural slab that holds the oven not the cooking floor lol!!! I was just hoping to get advise on how thick do most use 4 or 5" I will be using ceramic fiber board as an insulated layer not vermiculite and of course the firebrick on top for the cooking floor
