Alt-tag change site logo

[raicap]

I use prestashop 1.7.7.2, it happens to me that changing the logo from the BO, loading a file with a certain name, this is automatically renamed. EXAMPLE: the site is called (pincopallino.com) I load a file called pinco.jpg and in the file manager I read pincopallino-logo-16587699. I think I understand that when I upload a file it renames it with the name of the site and this is fine, but it also puts that - logo - into it, this produces an alt-tag like pincopallino-logo-165 ... and consequently a indexing on the web with a pincopallino logo title. In practice I would like to exclude logos in the web search. Obviously pincopallino is a fancy name. I hope I was clear. Has anyone had the same problem?

Thank you for your quick reply and I apologize for my google translated english. But perhaps my request is not clear, I am attaching a screenshot of the research done for "LO SMERALDO CAPECE GIOIELLIERI" which is my site, as you can see in the search the word LOGO appears which should not appear, because it is not present in the name of the file, but it is set by the system. Basically I load a file called losmeraldo.jpg and the system renames it in "lo-smeraldo-capece-gioiellieri-logo-1634567 .... jpg", as you can see, if on google I do a search like "lo smeraldo capece gioiellieri "appears with the words LOGO.
