As for the problem you're describing, you're correct that by default the system will only allow two images side by side. There is a block in the 'layouts' section along the left side of your screen, which contains 3 columns. That 3 column block will allow you to put three images side by side. If you need more than three images, then the best method is create a single larger image, that contains all of the content that you're attempting to insert within that row of images.
