Hi,
You might be managing several websites and contacting us for different websites on different threads at the same time.
For example, following your message here, I checked your recent thread 2 days ago here
www.hikashop.com/forum/customers/908584-...sterationnumber.html
and found a website URL which doesn't work:

Please understand that we have to answer to many users for many websites and we can't keep track of the URLs of all the websites of everyone.
Now, you posted today about another issue on
www.hikashop.com/forum/install-update/90...ges-and-content.html
where you provided another URL and on this URL, I can see that you have added custom classes to the div elements of the product page layout in order to rely on your template's CSS:

As you can see, the left side div has the class size-35 with has a 35% width CSS rule in the CSS of your template.
This forces the area available to be maximum 400px. And since you also have CSS to force the image's max width to not go over the available space, even if you configure HikaShop to generate an image with a width of 800px, the browser will resize it to fit in that area of 400px.
