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.

  • Hearth build up / strength question

    Ok, I'm totally a newbie on this and am learning as I go. I have built my stand (a corner model) for an angled 42" oven. I poured the concrete slab for the hearth base and then the perlite/portland cement mix to the specs outlined in the plans. The perlite mix goes right to the edges of the hearth.

    My question is this: Given the structural limitations of the perlite/portland mix, what are my options for putting a finishing layer on the hearth to protect against moisture, or alternatively, can I build up walls and a roof on top of the hearth? Will the perlite/portland mix hold up with the weight?

    In retrospect, I probably should have formed it off to limit the perlite to just beyond the perimeter of the dome, but it is too late for that.

    Any thoughts sincerely appreciated.

    It is easy enough to remove the perlcrete from the area where your walls will be, and that is what you will need to do.

      Thank you for asking this question! We did the same thing, but ran short of the perlite/concrete mix.

      Tscarborough, do you mean we'll need to chip off any perlite mix that does not go right under the dome? Many thanks in advance, Heather in Pittsburgh

        Yes. Cut back the perlite to just short of the dome. If not, and depending on your finish, this layer could be a constant source of water entry.

        The way to thing of this is to draw a circle - this is the inside of the oven. Draw a circle around that - this is the brick and hearth brick, the thermal mass. Another circle around that - this is the insulation. Another circle around that- this is the support slab and finish/cladding.

          Just one more question. If we are going to put a layer of tile on top of the perlite level, would we still need to cut it back? Would we be better served to do so anyway?

          Many thanks!
