I am not sure what riskware warning means. Are you using some plugin that is (falsely) identifying the download as a potential threat? When I try the link I see it as expired because ufile.io only allows free access for a month in order to sell premium access. I uploaded this as an example, not as an indelible long term file I was guaranteeing access to forever. The file itself is just a zip of jpg images, there is no risk of viruses because there are no executable files.
Plus, this was just an example. None of those images were particularly great. If anyone wants me to upload my "best of" archives in landscape and portrait again, I would be happy to do so and I think they will download just fine.
If ufile.io is not considered a safe site, I can try to find another option.
