title: Confusion on google api query limit for chrome extension
body: <p>I'm super new to making chrome extensions, but I really wanted to make one that let me highlight text and just do a simple same-page google image search of that text by clicking the extension button and opening a popup of the returned images from the query. <br><br>So I made it and tested it using the deprecated google image search api. I want to put it live but I'm genuinely confused about the query limits. I have no intention to make money off of it in any way, considering the primary content of the extension is just a google image search. I just always hated having to open a new tab to search for images of a word I see on a website when surfing the web.</p>
  
  <p>Also is it even possible to upload it to the store when it's using the deprecated google image search api that still works for some reason even without a key. Or would I need to update it to using the custom search api, which has only free 100 queries per day. And can someone explain that? <br><br>If it's an extension, and a end user clicks on the extension button and it queries google custom search api, I'd only have 99 queries left for that day? So only about 2-5 people could actively use it during the day before the limit is reached? I spent hours reading stuff but I still don't quite understand.</p>
