When I duplicate a sheet, all the hyperlinks attached to images in the sheet are not copied. In cell hyperlinks are fine.
Same issue when I use Sheet/Move or Copy Sheet.
I thought I’d see if copy/paste individual images had the same issue and it does.
This bug is a little bit moot at the moment as hyprlinks on objects aren’t exported to pdf anyway. [bug142296] (142296 – Hyperlinks set on an object in Calc are not exported in PDF documents)
Unless anyone can report a ‘works for me’ I’ll have a better look in bugzilla and log another bug.
