Does anyone know how I enlarge my photos? I added my images and they are now just thumbnails. Am guessing this is very simple to resolve, and I'm clueless!!! Thanks in advance

Images are set by their size (layout tab) (dimensions) default is usually max=200px so just increase that to whatever size you want at whichever breakpoint you want, or select size = none and it is then controlled by the width of the parent container (if it has one)
