Full Screen Web Gallery

Okay, for some reason the order inside Lightroom.adobe.com is not the same as in LRC 😞 🤔 🤔

Ahhhhhhhh, all good guys. I found the option at the bottoum for custom order. 😀
Thanks so far for supporting me 🙂

If you mean in person, rather than on the Web:

get the desired sequence of images showing in your Filmstrip - Collection, Folder, filtered / sorted as you want. View the first image of that - doing this in Library will probably be a little quicker.

Make sure you are viewing the image with Fit zoom - or Fill zoom if you prefer. Fit will show the whole image plus black margins otherwise - as needed depending on its shape. Fill will show no black margins, at the cost of showing only part of your image - as needed depending on its shape. Fit is best way to go IMO.

Press F key to take the image fullscreen, then use the keyboard arrow keys to step through your sequence. Press F key again to come out of fullscreen mode.

It is also possible to display images to fill one screen, as you step through those using e.g. a Grid view on another screen. So that would help you collaboratively work with your client on developing a selection.

Also: even while viewing images fullscreen on a single display, you can still flag / rate them or even cull (for a collection, deleting an image's membership in that), whatever, using the keyboard.
