When I direct access image “https://guiavitrine.com.br/bemvindo/wp-content/plugins/images-thumbnail-sliderv1/imagestoscroll/Logo%20Hoteis%20Seara-3Hoteis.jpg”

I got following error in your theme

https://guiavitrine.com.br/bemvindo/wp-content/plugins/images-thumbnail-sliderv1/imagestoscroll/Logo%20Hoteis%20Seara-3Hoteis.jpg

So may be something wrong with it ask your theme designer.

Thanks
