Gemini_api_image_url file size and token count is not match

So, I’m Currently working on a test with gemini llm with input Image + Text Prompt.
but I found that every test Image that i sent (with varient pixel size) to the gemini api return only 258 input token (with 1024 x 1024 or 768 x 1280 pixel image)

I think following gemini docs this gemini docs, the input token has to be more than 258 token. is this right? or gemini api automaticaly resize input image??

my test code and screen shot :


testing with 2.5-flash with 3840 X 2160 jpeg has same 258 image token…
and 2.5-pro also has same result.
