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.

  • refractory concrete hearth?

    Hi guys,

    I'm part way through a build, refining the design as I go. For a bunch of reasons to do with limited space and a liking for the small and efficient over the big and meaty, I'm going for a cast refractory concrete dome, 33"ish diameter, and 2"ish thick. I know this is a lot thinner than the standard half brick, so there will be less thermal mass - that's a good thing as far as quick heat-up goes, but I know I need to be very careful on the insulation to try to keep the heat in. I also know there has to be a much higher chance of it collapsing than a brick dome - that's a risk I'm prepared to take ;-)

    Anyway, my real question is about the hearth. With a thinner than usual dome, a thinner than usual hearth seems pretty sensible. So I'm thinking 2" or a touch less. I'll have a bunch of refractory concrete available, and I'm wondering if anyone has used that for a hearth, or has any good thoughts about whether it will be a good thing or a bad thing. I've seem quite a few refractory concrete domes now, but no hearths - is there a good reason why which I'm missing?

    I know you can get thinner firebricks, and I know they are well proven, so they are obviously an option. But I don't mind experimenting and being the fall-guy for something new - unless someone knows a good reason not to!


    Dave.
