Can't add anything else to the Main Page

I recently removed all the items in the main body of my main page.
When I started to put pictures back on, I noticed that I now cannot add any more pictures than there is now without everything in the main body of the page stretching over to the right, over the right hand column. I used to have many more pictures in the main body than there are now & I don't know what I've done to make this no longer an option.
Hope someone can help, my web address is https://www.BlackburnModels.com

Where and how exactly did you want to add the other pictures?

Try adding some so we can see the problem.

If you're adding them using the define pages editor in admin/tools, then remember you have to use html code there. So add BR tags or set them all up in a table or whatever works to align them how you wish.

Many thanks for your suggestions - I think I'll try using a table.
