Off Topic: But hoping for advice anyway - Slideshow plugins?
 

Need to add a slideshow option to the site.
Not all pictures are the same size and shape. Some are portrait, some landscape. I could, I suppose, make at least all of the widths all the same, but I'd rather not ask the client to do that once I turn the site over.
Also, all pictures in the slideshow should display captions. And I don't want long captions to overflow the width of the picture.

Have tried NextGEN Gallery, Portfolio slideshow, Gallery Slideshow, Slideshow and Slideshow Gallery. Either they do not do what I want or they are too difficult to configure.

Thanks for any advice.

Regards

I like 'WP Lightbox 2' - You use galleries you create in the WordPress media library and the gallery short code. You just add a 'del=files' to the gallery short code and you are all set.

I like Soliloquy. It is a premium plugin.
