I'm working on a project that requires previews for related websites. We've been playing with a couple ideas, and two that have come up are using a service to render the website and send back a screenshot, or fetching the website and loading it in iframes as a 'live preview'.
The team is convinced that the iframes are the better option, since they would be interactive, and allow for dynamic visuals to be previewed, but I have some performance concerns.
Just wondering if anyone could offer some insights here, without coding up a server to fetch the website content and forward it to the site. The designs would have about 5 images/iframes, relatively small ~300x500 pixels. Would loading the 5 iframes be analogous to opening those sites in 5 tabs?
