The photos do not show up when clicked on. I have tried the front page photo gallery, and have not had much luck with it. I am sure others will put in links for photo gallerys, but I just do it the simple way.
I create a table with four rows and four columns, Insert table, then specify the amount of rows and columns you want. Fix the width at 90% and at the bottom put the border to nil. You can then just put in a photo to each cell.
I know that it is not as fancy as some, but it is easy, and it does work. Of course as you know, you will have to 'control and T' to every picture to create the thumbnail.
