SEO 100 images gallery on single page

Hi, I've been creating multiple choice mock test videos using Inkscape to create images with the questions and answers embedded and uploading them to yt.

I want to include these tests on my site but, the content is public domain so everywhere. I was thinking of creating 3 posts 1 for each test, some words about them and an image gallery to browse through them.

Thing is there's a fair few images;
test1: 40q + 40a = 100 images
test2: 50q + 40a = 80 images
test3: 30q + 30a = 60 images

I know this would decrease the loading times of these pages alot which is not great! Would it be better to have separate pages for each image? that would be very thin content though as the pages would only include the image. Your thoughts would be great?

anyone?

If your site is ranking well, or you make use of PPC or other ad campaigns, thin content matters very little. Thing is, IF you manage to get a thin content (in your case, "click next page to continue") kind of pages, this can actually increase your SEO as it decreases bounce rates and increases "user activity" on your site. Meaning people who land on your page through organic links will visit 2+ pages, which is great and will give your site a boost.

And as you mentioned yourself, more images on a page = slower loading times unless you use proper web hosting (more expensive business packages) or CDN networks, which is very bad for SEO. These types of sites you're referring to do very well on social media sites and PPC if done right. All about split testing to maximize ROI

thanks, at this time the site is new and does not have much content, maybe something for the future.
