The filters for web search allow to set a time/date range similar to Google search (including a custom range). However the same is not the case for "Images" and "Videos" searches on Kagi.
Images search can only be set to: Any or Past Day/Week/Month/Year. Videos search stops at "Month" and doesn't even allow "Year". Both do not provide a custom range option. This is however possible with Google searches.
A flexible filtering for date ranges can improve the quality of search results. For example to filter out potential outdated content.
