Images Sitemap not indexing subdirectories

[urus.shaitan]

Hi,

The addon 'images_sitemap' is checking my folder /img/, and indexing one image at that level. But there are several subdirectories under /img/ that it's ignoring.
I tried adding 'optional inclusion mask', but I don't think i'm understanding the syntax correctly.

What can I do to point it to the right folder - it should be '/img/uploads/desktop'

Thanks!

Hello,

what is the page URL when image embedded that is not added in sitemap? (and image URL)

[urus.shaitan]

thanks Oleg,

The page is [ External links are visible to forum administrators only ].

'Images sitemap' is finding [ External links are visible to forum administrators only ], and shows only one gif that's  in that folder.
But inside that fiolder there is also subfolder /uploads/desktop/, which has 1,600 images that i need to index.
