FYI, I've had to revert the site back to 3.9.

I've also attached a picture of the functionality that I am trying to locate in 5.0.4

Hi Sharon Dibb,

Kindly find my response for your inquiries below:
2. I have just updated from 3.9 to 5.0.4 and I use the Image Wall module extensively on the site. In 3.9 it used to pull the image sizing from the theme. In 5.0.4 I can't work out how to change the thumbnail size so that it flows through into the module. I have set the thumbnail size under Settings>Media but it's not doing anything.
-> In EasyBlog 5 we have remove the image height and width setting in the Image wall module,is because we have receive a lot of user complaint as the image was not shows beautifully and make their layout broken if the image was fix to the setting with varies of positions, as now we have make the image shows correctly if user put it in varies of position (banner, sidebar etc) so the image will be fit in each positions (and caused the site layout not broken and more responsive in view)
However, you can resize it by apply simple css code in your site, perhaps you can try add the css code below:

div#fd.eb.eb-mod.mod-easyblogimagewall.ezb-mod .ezb-grid a.ezb-card {

    height: 251px !important;

    width: 250px !important;

}

I've also attached a picture of the functionality that I am trying to locate in 5.0.4
-> For this setting, we actually have revamp the setting layout so it will be standardize and simplify in views
You actually can find those setting in (component>easyblog>settings>layout)
