I can't unhide photos of me on my facebook timeline?

[Cofi]

I've accidentally hidden some photos that I was tagged in. And I searched facebook options for hours and haven't found obvious answer on my question. They're shown when I look at my photos, I just want to get them back on my timeline... Thank you in advance for help.

Unfortunetly, activity log sais that they're allowed on my timeline, but wheng i go there, they're not showed (probably because I've hid them and now whatever I do I can't undo it). Only when I higlight them, they're shown as separate, large photos. It seems to me like there's no solution. I mean, allowed on timeline is checked, but they just won't show... help
