Hi there, tables do not play well with responsive designed themes, such as Gather. The table will always stay 3 columns. We can get things to adjust, but the images would be very tiny on a smaller phone in portrait orientation and virtually impossible to tap on.
What I would suggest is that you edit that page, remove the table and reinsert your images singly and switch to the Text tab and add a CSS class to each of the image HTML tags, similar to this:
<img class="my-svc alignnone wp-image-..."
What I added was the my-svc class.
Also, surround all the content within a div with a CSS class like this.
All your image code here
Let me know when you have that done and I can work on getting things into columns and include the Media Queries necessary to get it to work on all size screens. What I will do is display 3 columns on wider screens, then drop to 2 when it looks like things are getting crowded, and then finally to 1 column on smaller screens (phones and small tablets).
