It is extremely difficult to delete a photo added by an internet user, unless it violates Google's guidelines. These are listed in Google's Help Center under Prohibited and Restricted Content and Format Requirements.

List of restricted content: "Spam and fake content, off-topic, restricted content, illegal or sexually explicit content, shocking, dangerous and degrading, impersonation, conflict of interest"

To be relevant, photos or videos must be taken by users at the location in question: stock images are not relevant and may be removed (this does not mean they will be).

Stylistic adjustments, such as filters, are tolerated provided they are minimal (no borders, text, montages, etc.).

Any content that prevents proper viewing of the environment may be rejected: too dark, too blurry, rotations or overly strong filters.

Image resolution must be sufficient (requirements vary depending on photo type and import source).

Do not upload screenshots, drawings, posters, or other non-photographic content (except videos).
