Photo's title get original file's name

Hello. I found lots of search topics about it, but didn't get answer on my question.
When user add photo, it get title (basing on filename?).
For example "30C4E37A-04AF-42E9-8116-44EA32E7A03C".
It will not help me to serch photo and seems not usefull. So I hide it with css:

.es-photo-title{
display: none !important;}

What I missed? May be I break something important by hidding it?

Title field still can be edited by user and used for searching (if smart search used)? But what else? 99% users doesn't fill this field. Why ES display photo title?

Thanks.
