I thank anyone who can help with this problem on my google sites, I have several years with this account and I have uploaded a lot of google drive and google photo material (they are linked) without any problem on my classic google sites website, and for a few days for some reason that I do not know, they stopped seeing, check the permissions of the google sites (share with everyone on the web) and check the permissions on driver and photos (share with everyone with the link) but still you can not visualize, thanks in advance
