Hi
A) I don’t know what an ACF is but my guess is no. See the other answer for the reason.
B & C) I’m afraid not. The plugin uses a public WordPress.com api to generate the screenshots. Everything is on a third party server that I have no control over. The limitation of getting this for free is that we have no control over it 🙁
Hello ACF means advanced custom fields. It’s a very popular plugin.
Ah ha – that makes sense. I’ve heard of it but never used it.
If you are storing a url in a field then that could be used to generate a screenshot.
There’s an example in the readme that looks like this:
<img src="<?php echo BrowserShots::get_shot( 'https://prothemedesign.com', 600, 450 ); ?>" />
You would need to replace the url with the one you are storing in the field.
Thanks – Ben
