Solution to "Could not load image (1,019)
I tried everything to solve this issue android all the threads but never found a solid answer to this 0,019 error. (There may be one but I couldn't find it.) Today I tried something new and it worked so I thought I should share.
I selected the Photos Library in the Pictures folder. Using the Control key (or a right click) I selected from the pulldown menu the Show Package Contents option.
There were two folders mixed in with the others that were Masters collections. One is the Masters folder for Photos. The other holds the Masters from my older iPhoto library.
I simply moved all of the folders holding iPhoto Masters to the Photos Master folder and presto!
Next time I opened Photos I could export anything and everything.
I ran Disk Utility to repair permissions just in case but so far... no problems.
Good luck.
