The reverse image search announcement says you can reverse image search by navigating to "Images" and clicking the image icon in the search bar. But this is not really true - you can only do this by first making a regular search, because on the main page (kagi.com), clicking "Images" does not cause the image icon to appear in the search bar. It only appears on the search results page.
The reverse image search icon should appear in the search bar on any page where a kagi search bar exists, provided the "Images" option is selected. See google.com for example (The last button in the search bar is the relevant one. In fact, on google, you don't even need to click "Images", and there is no "Images" button on the main page at all, only a "search by image" button):
The current state of reverse image search on kagi isn't ideal UX because I don't want to make a regular search when I'm using this feature, and users would never guess that they have to make a boilerplate text search before they can make a reverse image search. I guess this is especially bad here because I think there are plans where you have a limited number of searches per month, causing you to waste one every time you do a reverse image search?
Thank you for your consideration.
