Find Duplicate Report Media False Positive with Similar File Names
When file names of two different but related images are named: someMonument.jpg someMonument_2.jpg
or someMonument.jpg someMonument_back.jpg
The algorithm flags these are duplicates even though they are completely different images.
Yes, that is expected.
The "find duplicate" tools are all designed to find "potential duplicates". In this case (media) the system only compares the file name for a close match. It's for you to decide if they are actually duplicates on your site. It is always challenging to be 100% accurate declaring records as duplicates.
If they are not duplicates you can:
1 - ignore them 2 - change the file name more significantly (eg use random codes as file names) 3 - for media duplicates always add a unique "descriptive title". Then they will not be regarded as duplicates.
This is working as designed. webtrees only compares the titles of the images.
It should be noted that to comply with accessibility standards, images on a page should all have unique titles. webtrees can't do this for you. You need to select the names yourself.
If you have two images called "Monument", then it would be good practice to rename them to something like "Monument (front)" and "Monument (back)".
On a related theme, it is entirely valid to have two media objects refering to the same media file. For example you could have the same photo used in two different media objects, with titles:
- "Jack (left) with his older brother Paul"
- "Paul (right) with his younger brother Jack"
