Yes, you're probably right. It is one of three products in a line, so I guess it's a product block rather than a pure image block. But if I go to the product underlying it there seems to be no way of editing the size of the image. There are filters, and cropping tools, but they alter the actual image, not the size of it (like if I cropped the image I would lose the top of the bottle, for example). Also, if I upload an image from my computer, changing the size of the image makes hardly any difference to the size of the image uploaded to the product. The photo file was originally 4mb and 4000 odd pixels wide. The product image on my page resulting was huge. So I cropped the image before I uploaded it and uploaded it again. It's still much larger than the adjacent images. Then I checked the size of the adjacent images and they're 4mb files 4500 pixels wide. I don't get it? How are they comparatively small and the one I've uploaded, which is a fraction of the pixel dimensions, showing as twice the size? Also, is there no way to crop the image once it's in the asset library? It seems to be guesswork what size image to upload to match existing image files, which can't be right. I must be doing something basic wrong.
