Ahhah OK I see - though the problem with a 'back' button as a website button is that it's obviously going to be different depending on how you got to the page, and especially weird if you arrive there from a search engine or external site.

I think the only good long-term answer here is that I should add the ability to add embedded YouTube videos either to the assets library (so you can use the Related Image Gallery includelet to make a gallery) or to the Photo Album app.

(i.e., insead of adding a video file, you simply add the YouTube video id/url, and then this gets embedded on the site rather than a photo)

You can currently mix video and photo only if you upload the videos into the assets library then use the Related Image Gallery includelet, as outlined here.

I have a browser plugin for Firefox called SaveFrom.net helper that lets me easily download a video file as MP4 from your embedded YouTube videos, and even the longer ones are only about 25MB in 720p quality.

So, while it would be a bit of faff, you could download each video as an MP4 file, upload them to the Assets Library (then add the photos too!) then create some nice gallery pages using the CMS.

I appreciate this is a bit tedious, especially as you can't bulk upload photos to the assets library, but I think you'll end up with a really nice gallery page this way! Neater than having to embed each video on a separate page to the photos.

Cheers
