Quick Fix: Gemini "Wrong Image" Download Bug

If you are generating images with Gemini’s new Nano Banana models, the "Download" button is currently broken. It frequently downloads an entirely different image from a previous prompt. 😭

The official fix isn't out yet, but the high-res asset exists. You just have to bypass the broken UI to get it.

The Fix

Don't use the download button. Do this instead:

1. Open the Image: Right-click the generated image in chat and select "Open image in new tab."
2. Edit the URL: Look at the address bar. At the very end, you will see a parameter that looks like s1024-rj.
   • Note: s1024 limits the image to the chat preview size.
3. Swap the Value: Delete s1024-rj and replace it with s2752.
4. Save: Hit Enter to load the full-resolution master file, then right-click and "Save Image As."

What's happening under the hood?

In Google’s image serving architecture, the s parameter controls dynamic resizing. By manually requesting s2752, you are forcing the server to deliver the native, uncompressed output of the same image. 🎉

It’s a classic case of a fragile UI layer failing while the backend works perfectly—sometimes you just have to ignore the button and query the source of truth yourself.
