Preview Plugin

[phenomlab]

@julian Yes, thanks. Actually, I think I narrowed down the issue. There is a fork of nodebb-plugin-rss that I am using called nodebb-plugin-rss-brad - I think the changes here are that it renders other HTML (description - like v1.3 of the official NodeBB version did), so I went for that.

I think it is that plugin that adds "Via: " as it is doing it on all links, and not on my other site which uses the stock NodeBB version.

Let me confirm, and if so, this can be closed.

my site use this plugin ,no image,why?

@huige There are some sites that use hotlinking protection to prevent the images being returned - not much we can do to fix that either. Does this happen on all preview renders, or a select few?

@huige Are you using CloudFlare?

@phenomlab
I didn't use cloudflare, and I tested it again, and the link on my site can be parsed normally in the post, is it a cross-domain problem?

@huige Do you have any headers set which restrict the ability for sites to display the images?
