Question

I would like to know how to enlarge the images on the pages of products.

Answer 1

Go to your theme/template/catalog/view/media.phtml and change this

<img id="image-main"
            itemprop="image"
             class="gallery-image visible"
             src="<?php echo $this->helper('catalog/image')->init($_product, 'image') ?>"
             alt="<?php echo $this->escapeHtml($this->getImageLabel()) ?>"
             title="<?php echo $this->escapeHtml($this->getImageLabel()); ?>" />

to

<?php echo '<img id="image" src="'.$this->helper('catalog/image')->init($_product, 'image')->keepAspectRatio(true)->keepFrame(true)->resize(1035, 692).'" alt="'.$this->escapeHtml($this->getImageLabel()).'" title="'.$this->escapeHtml($this->getImageLabel()).'"/>';?>

See this resize(1035, 692) section, it is telling that make image's size to 1035px × 692px.

Hope this helps.
