The developers of Gallery2 have developed an excellent "preinstaller." It is a small file (roughly 23K) that users upload to their site. This preinstaller connects to Gallery's servers (actually Sourceforge's, I think), downloads the zipped software directly to the host's computer, sets up the databases, and unzips the software.
I don't know enough about coding to contribute a similar tool to Wordpress, but I suspect that if somebody could develop such a tool, it would have these major advantages:
- Faster installation for folks using FTP without command line access (because it takes a while to download to my computer, unzip, then upload the unzipped Wordpress software to my host).
- Fewer problems in this forum
So, any developers want to take this up? Here's a link to the Gallery preinstaller.
