Restore only partial iphone backup

Dear all,

Is it possible to only restore / retrieve the pictures out of an iPhone backup file (and ideally merge them with a new set of pictures)?

I lost all my data a few weeks ago when doing an iPhone software update, then restored a backup from iCloud but only found out much later that that didn't include my picture library. I do have that picture library in a backup file on my computer somewhere, so now I'd like to extract those pictures from it and merge it with the new picture library that has now build up on my phone over the past weeks.

Thanks in advance for your help.

Best regards,

Tim Metz
