Website Building - Failed Attempt

I decided to throw together a basic website idea to present to Katy for a reference of how her artwork would be presented. The process is shown below...

Firstly, I chose a basic template, and altered the text (just to test it was a good template for the job). I specifically chose a 'portfolio'-defined template, as I know we want the website to be as visual as possible...

I then went through each of the pages, changing titles and SEO settings (what the URL for the page is, what the title for that page come up in the browser tab)...

Unfortunately, at this point, Weebly showed it couldn't handle the size of the images needed to upload. Due to this, I will have to try with Wix, which could be good, as it's a site I've already used. This is a shame, however, as I was really enjoying working through Weebly.
