Hi. My wife and I are making our own website. Our skills are limited, I did a course on HTML and CSS and showed her some of that. We have managed to find our way to where we have made a nice enough looking and functioning site and are ready to launch it, but for a gallery page. I was content with just a regular page with a bunch of nice pictures with descriptions- my wife (credit to her) said that was boring and pointed to a few websites that have what I believe is 'flash' or 'java' type gallery pages. I have NO idea how to make this, so anyone want to help I would appreciate that, thank you.
I can't do the work for you, but I'm more than happy to help you along the way.
The second step is to play with a few tutorials on the site to get a rough understanding of the basics.
The third step is reading the documentation for the Galleria jQuery script you posted. It is of great help if you study the source code of the demo page.
Should there be any problems, post your code, so that we can guide you through.
