Hi Alexis,
Thank you for writing in, I see you wrote your image element like this:
<img class="alignnone size-medium wp-image-205" src="../wp-content/uploads/2018/12/48373831_311765659437571_5897723553268105216_n-300x67.jpg" alt="" width="300" height="67">
That leading two periods on your src is the issue, because that means up one folder directory, so your src now will look for the image here: http://alexcamacho.co.uk/wp-content/uploads, while your actual image is located here http://alexcamacho.co.uk/sohofc/wp-content/uploads
Please update your image src to this:
src="/sohofc/wp-content/uploads/2018/12/48373831_311765659437571_5897723553268105216_n-300x67.jpg"
Or better use the absolute link:
src="http://alexcamacho.co.uk/sohofc/wp-content/uploads/2018/12/48373831_311765659437571_5897723553268105216_n-300x67.jpg"
To make sure that src will be updated once you do the find and replace when you migrate the site to live later on.
Hope it helps,
Cheers!
