Images not showing up

I can install wordpress fine but I’ve never actually been bothered to have a go at doing a layout for it as it has always looked so complicated. But now I’m sick of relying on friends to do the layouts for me so am doing it myself this time round.

This isn’t a blog, but a place where I can post my photos too, I wanted it to have comments so I figured wordpress would be the best tool for this.
I used; https://www.techwench.com/wp/entry/wordpress_15_theme_cheet_sheet/

But my images arn’t showing up, see here; https://elmiee.be/Bloggie/

I did the layout in photoshop like I always do first, then I coded it in CSS and then added the wordpress parts. In photoshop it looks like – https://www.irismemoirs.org/pictures/Untitled-2.jpg
and that’s how I’d like it to look at the end, for it to have just one image on the front.

I’m not sure where to start looking or why the images arn’t showing up?
