If someone can view my site http://monalisasarees.com/, you can see the images used below the slider are blurry. The actual image uploaded is a larger one but the theme(PowerHub) somehow resizes the image to a specific size.
Same goes for the single product page images.
Can someone point me some right direction where I can adjust the image size so that I can set the image to any higher dimension to overcome this blurriness of image.
You should know that some of the setting you can manage from 'administration --> Configuration --> Settings --> Media settings'. Once you get there look for this setting 'Category thumbnail image size:' and write the proper value.
