It's guessing!

Can't be bothered trying to figure this out.

I somehow managed to get a rough umbrella shape and then filled in the rest of the puzzle. The image is nice, but there are multiple possible solutions.

**SPOILER**
R2 C12,18 ; R4 C10 ; R6 C20 ; R8 C4,18 ; R10 C3 ; R11 C1,4 ; R20 C9,15,20 ; R22 C3,7,12,14.

Thank you so much for your support, Strigoli !!

Thanks Strigoli would never have solved this without spoilers, don't know how you managed it.

Thanks Strigoli.

Great work Strigoii, thanks for the hints.

Nice picture, but a horrendous puzzle! Those hints were perfect though, and then it became a good challenge!
