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 have read the archived posts on stucco and render but still have a few questions. Thanks for any help.

    I have a bunch more firings before I put the 2 render coats on my vermicrete layer. The vermicrete has formed some large expansion cracks that open and close with temp changes. I plan on using surface bonding cement with the liquid additive to form the stucco layer which I will later paint with stucco masonry paint.

    I read that you would first fill in the cracks with SBC before the first layer goes on. If I cover the cracks when the oven is cool, I don't understand how the cracks won't bust through the stucco layers when heated up. How do you handle the expansion cracks so they don't crack the stucco?

    Also, how long should you wait after the first coat before putting the finishing stucco coat on the oven?
    Thanks

    Don't worry about the vermicrete layer cracks. The layer is not structural. The only reason to add cement, and therefore water is so the stuff will stand up vertically on its own. If adding vermicrete to an enclosure style oven it is better to add the vermiculite dry. The problem you now have is that you have to eliminate the water otherwise the steam pressure can crack the outer stucco.the dryly vermicrete is slightly elastic anyway so won't cause a problem so long as it's dry. Try placing some plastic sheet when firing, over the vermicrete to test if water condenses under it to test if all the water is eliminated from the vermicrete.

      Thank you David, but even if the vermicrete layer is dried out, won't the cracks that already exist continue to expand and contract as the oven is fired? If the cracks go up and down based on when the oven is hot/cold, then how do you prevent the stucco layer from cracking also?

        As he said, the vermicrete is not structural, i.e. it will not mirror through the render/stucco. Do not fill the cracks with SBC (that is for structural, non thermal crack repair), fill them with either loose vermiculite or a very high ratio vermicrete (like 8 or 10 to 1).
