How to properly show images to players?

Hi everyone, I'm new to roll20 and I plan to run a game of Trail of Cthulhu for some my friends. As you may know, Trail of Cthulhu is mostly about investigation and scary vibes. I don't need to use maps and I will only show images such as landscapes and monuments to the players. Those image are quite important for the scary ambience in the scenario and I would like them to be displayed properly. I uploaded them, one per "page" but I am not quite satisfied with the rendering. I would like them to open in "full screen" for the players and not as an image paste inside a broader white page. Is that possible to do that with roll20? Thank you in advance for your answers, Jules :)

Two methods you could try: 1. Set them up as "handouts" in the journal.  (new handout, name it, add the image). They will have the option to click on it once you show it to them for full size.  2. Put them on the GM layer, but then use "Shift z" to have them pop up for everyone. 

Have you tried using the browser's fullscreen mode (F11) and perhaps minimizing chat and/or using a bookmarklet(I believe this only works with chrome) to hide most of the roll20 gui (see the end of this page on the wiki:&nbsp; <a href="https://wiki.roll20.net/Using_Roll20_while_Playing" rel="nofollow">https://wiki.roll20.net/Using_Roll20_while_Playing</a>... )?&nbsp; This would need to be done voluntarily by all player's. You could then either display pages with images at full screen, use SHIFT+Z on token images at their max size(you'll need to make sure your images are very large to fill screens, you'll probably need to experiment with this...), or even make a&nbsp; rollable table token with multiple images and use SHIFT+Z to display full view to the players.&nbsp; Or any combination of the above. some "Gold"en info in this post as well:&nbsp; <a href="https://app.roll20.net/forum/post/4135888/slug%7D" rel="nofollow">https://app.roll20.net/forum/post/4135888/slug%7D</a>

Thank you very much to both of you Michael and Vince, your methods are fine, it's a big improvement for me :) Best regards, Jules

I still stand-by all that -- the large page as a canvas, with Shift-Ping to bring the players focus, and the Shift-Z to pop up full size pics. Those are my go-to techniques for this. I like Vince's idea of a Rollable Table Token + Shift-Z, as a kind of slide-show viewer built in Roll20.

Also, as a further refinement, I would suggest making the page background black. It will reduce glare, be less distracting and hopefully support the ambience you are looking for. To make it even simpler, you can put fog of war over the entire page (the manual kind). Then place your scenes on the page, naming them as if they were tokens: Creepy Forest, Library, University Catacombs, etc. The players won't be able to see any of them, hidden by the fog, but they will appear with the shift-z. You of course will be able to see them just fine, especially if you reduce the GM opacity on FoW.

Thank you, Keithcurtis ! I did not think about the black background
