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.

  • Vermiculite concrete under brick arch

    Hi everyone,
    Quick question- I have built my oven base on a thick slab and then made a 12cm slab on top of the base bricks, I would like to add a concrete vermiculite mix on top of that slab/underneath my oven floor for heat retention... here the question: will the vermiculite concrete be strong enough to hold the brick arch and floor tiles? I had a look at vermiculite yesterday and it seems very light... Do I have to put another layer of concrete on top for stability? Thanks for your help…

    Hello,

    I moved this to Getting Started, so you can get more input. The short answer is Yes.

    Vermiculite is pretty odd stuff (it's basically volcanic popcorn), and it does seem light and not very stable, but is will set and become solid and it has very, very good compression strength. Your oven will be solid!

        It dries to a cork like consistency. It will flake off at the edges, but you mostly want to keep the edges covered anyway.

        In short: Vermiculite concrete has lots of compressive strength, but almost no tensile strength. It's used for swimming pools that are under tons of pressure.
