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.

    I found a local fire brick supplier for $1.05/brick. Composition is as follows:
    66.9% SiO2, 25.6% Al2O3, 2.5% Fe2O3, 2.6% alkali, 1.5% TiO2, etc. Recommended max operating temp is 2000 deg F.

    Does this look like the right stuff? I assuming SiO2 is silica of some sort and Al2O3 is Alumina of some sort but I really didn't pay too much attention in chemistry (it was an 8:00 am class)

    Re: Fire Brick

    I don't recall firebrick composition being in any of my chem. classes... so I think you're ok.

    How much does one brick weigh? I think a medium/low duty brick of the standard size should weigh about 9 pounds. Insulating firebrick, which you don't want, are lighter, and the high-duty ones, which are REALLY hard to cut, are heavier.

    I think the weight is in the plans from FB.

      Re: Fire Brick

      Thanks for the reply Elizabeth. The composition from the FB plans were 30% alumina and 50% silica. I believe weight should be approx 8 pounds. I know, 100% these are not insulating fire brick...way too heavy. The mfg rates them as 'low duty' but its the chemical composition I'm concerned with.

      If my assumptions are correct, are the differences in percentages (between FB plans and mfg product data literaure) a big deal? Therefore the silica content would be approximately 15% more and the alumina content approximately 4% low.

      also, i just spoke with a chemical engineer. he indicated that my assujptions are correct.

        Re: Fire Brick

        In my research (almost 2 yrs ago), I found "low duty" to be from 24% to 35% alumina, depending on the manufacturer. None of my findings came from a chemical engineer (I don't think you need one), all was based on data sheets and the info provided from several brick yards and a refractory supplier.
        That said, I chose "low duty" fireplace bricks that were 77 cents a piece, weighing around 8.4 to 8.5 lbs. I believe they are rated to 2100 degrees and have an alumina content of 26.5%........No cracks, no spalling, heats up quick, no issues at all.....you should be fine with you choice.
