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.

  • shape/strength of arch

    I need to decide on a shape for the entry arch. I like the kind where the sides go up straight for about three bricks, then begin to arch. (segmented arch?) Is this significantly stronger, or less strong than a full semicircle arch, where the arch starts lower?
    Here's mine:

    If you buttress enough it's as strong as any other arch.

    The difference between arches is how much lateral pressure they cause. Roughly speaking the less height the actual arch part has the more load it will pass to the walls either side of it.

      A hemispherical arch inherently has less side thrust than arches with vertical sides. You may find a discussion on arch/vault geometry and strength here:

      If you buttress either arch side thrust is not an issue.
