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.

  • Chemicals in Firebrick

    I have been searching for firebrick and I have had two dealers tell me that I shouldn't use their low or medium duty firebrick because the chemicals in it wil contaminate the food and possibly cause illness. They said that I should use transite bricks, which neither of the dealers sold, so I'm not concerned about a possible ulterior motice. Does anyone have any info for me on this possible problem?

    Thanks,

    Paulie Gee

    Re: Chemicals in Firebrick

    Hi Paulie,
    I had trouble buying 'reasonably priced' firebricks and settled on second hand ones.
    How dangerous will these be? I ask myself, BUT they were used for probably 50 years in a gas fired furnace to produce steam in an old abattoir.
    I would ask your suppliers for specification sheets of their products and show them on your posting for members comments. I think that we would also need to know if there are dangers lurking around in the materials we use.
    Every other manufacturer makes bricks that are safe and have been used without problems for years. Maybe they are playing safe, trying to avoid potential impending litigation!

        Paulie, this thread has taken a silly tone but your question is fair. Neill is correct, you can ask for specifications, but if you are buying new brick from a dealer you should be able to use them worry free, and low duty are fine. The time people have raised legitimate concern about firebrick and chemicals are when the bricks were used in a smelter and are possibly (probably?) contaminated with lead, arsenic, stuff you don't want in your food (heavy metal poisoning would make us all a bit too silly).

              In theory a typical brick should be on no more concern than the
              average rock, the kiln is basically a device to create metamorphic square rocks

                That is a good link, but I quit worrying about the chemicals in firebrick after I read Patrick’s petition – We’re doomed!!!!!

                      Hey now, that Dihydrogen Monoxide is some serious stuff. I hear it's a universal solvent, a leading cause of erosion, a co-factor in flooding, a contributor to mold infestation and a major factor in humidity. You can't be too careful with something like that.... <insert paranoid smilie here>

                          Dihydrogen monoxide is also one of the primary combustion products of wood ovens, but I'm sure James is working hard at solving that problem so we can get the EPA off our back. The vapor form is one of the primary contributors to the sweltering summer weather in the southeast, yet people self immerse themselves in the stuff as a coolant (Archena, is that risk taking or just lack of common sense?) - can this be moved to chit chat now?
