Some tasks seem to generate a lot of questions on the forum. Rather than answer the same questions over and over, we have made this thread to collect links to resources to help cover these common subjects.
As always, please feel free to search the forums. Many times, someone else has already provided a solution to the question you were about to ask.

First up: XML galleries. The following threads and tutorials should cover most of the questions you have on how to set these up and get them working.
