it's from here
http://www.kendahlin.com/web-design/1024px-version-of-crystalx/index.htmlOf course you have to change the path to the images and install it manually but it's easy.
Edit: a more detailed instruction:
- Install the original CrystalX design.
- Download the 1024x Version from the above link.
- unzip the package
- upload all files from the folder "design" of the unzipped archive to the folder "/public/cid<n>/CrystalX" of your bigace installation (where <n> is the number of your community)
- edit the file "css/main.css", change al entry containing "url("../design/<name of picture file>")" to "url("<name of picture file>")"
- if you changed the original stylesheet in the past you have to make these changes to the new stylesheet too, of course
- copy the text of your new stylesheet and paste in in the bigace administration into your stylesheet "CrystalX_Main_Stylesheet" instead of the text there.
that´s it. You have the 1024x version of CrystalX now.
