Home Automation web site Question .

Hi everyone.
I have a question about the site I built with HTML + CSS + Image.
The website has photos that are considering quite a few kilobytes so it makes me problems
And I use the SD card connected ethernet shield
The site is split into two parts. Buttons + home.
I want to ask if I could build a website to put it on my computer and not on the SD card
Then that arduino receives commands over the network from sits on the computer and not on the SD card connected to the ethernet shield
Thanks to all who can help…(I’m a bit new on this so sorry)
