upd. I downloaded the website and edited html-code (pic's urls moved from
styles to img src=""), and now there is no need to detect these links, so I
turned "Attempt to detect all links" = OFF ("Get HTML files first" is still
ON), but same warnings have appeared, and previously downloaded html-file has
downloaded again.




Some information that might help:

A) Website map:

1)
