If you have the latest Site Designer, version 4.0.3113, you should have a gallery component. You can find some more on my sharing site, see URL in my signature.

Does it allow sourcing images from a directory(s) instead of inline?

Yes you can use images places in your resources. Then simply right click the online placeholder image as select Edit Image then change to local image which will open your resources folder select the image you want there it is now a local src image

CROSS FADE!!!

Ability to set up individual links on each slide

Vary the Gallery capability

Will this be add on to the Responsive Content Slider?

Use the orbit component

Sorry, I just saw this. I was more referring to sourcing an entire gallery from a directory instead of coding a specific line of code per image. Something along the lines of \assets\pictures\ has 20 images. I want the images to load into the gallery automatically and change if any additional images are added to the directory automatically.

I do this now w/ php but it's a pain and resource hog

You can do this with an iframe popped into an html element.

have a link to an example?

I can't link to any example, so I made one up.

Of course, the source file needs to be updated when there is a change of images. This is not php, after all.

You may possibly be able to plan ahead, by writing the code for some, say 10 'images-to-be' call them img1, img1 etc, and then name your images accordingly when you have got them. And then just upload them

It may be that the following is not what is in mind, but if
1. what is wanted is just a responsive page of pictures of all shapes and sizes,
2. one is content for them to be displayed at the same width, and
3. one wants to load them from a directory in one go, rather than individually,
then the following, which uses SD4 in Windows, may be of interest.

(a) I create a container with a pixel-width set in the multi-column layout section;
(b) from Windows Explorer I select the pictures and drag them into that container;;
(c) I click Done (or choose other settings), and SD4 does the rest.

No doubt those who are CSS Grid experts will find better ways of doing this, but this is remarkably quick and easy, as shown in this screen-cast.
