Is it possible to group the images next to each other horizontally?

Is it possible to group the images next to each other horizontally?

I am looking at your form: http://form.jotform.com/form/60963332098359 and based on what you have mentioned I presume that you would like to set the images from this segment: Layout of Flowers  into a row of images.

Now it seems to me Catherine that the best way for you to arrange these could be through the usage of a specific widget: Image Radio Buttons

It will allow you to place the images one after the other - without need to think about their layout and allow you to add text under the same.

You can add the widget to your form by checking out the following guide: How to Add a Widget to your Form

Do let us know how it goes.
