Thanks @jarvis I also use bootstrap, but I did not want to say what should be used. :). In any case, the code needed is dependent on what is used. I was also thinking the OP was saying they would use a gallery field and did not think about using other types of fields. I have created galleries using a repeater for some clients when more than an image is needed like captions and the like. But in any case how the fields are used would be dependent on the code needed for whatever is used.
