In this article, I’ll walk you through how to make your own football poster—or honestly, any kind of sports poster you want—using nothing more than your photo and a ready-to-use AI prompt. The process is super fun, straightforward, and the results are so realistic that people might think you’re starring in an official campaign.

The best part? You don’t need to start from scratch. I’ve already prepared a powerful “magic prompt” that you can tweak for your own sport, team, or name. This means you’ll spend less time trying to figure out what to write and more time admiring your awesome new poster.

So, grab your favorite photo, pick the sport you love, and let’s dive right into it. By the end of this guide, you’ll know exactly how to turn a simple picture into a cinematic sports masterpiece.

Step 1: Preparing the Prompt

The key to making your sports poster shine is the prompt. This is basically the set of instructions you’ll give to the AI so it knows what kind of poster to create. Don’t worry—you don’t have to write it yourself. I’ve got you covered with a ready-made prompt that works for football, basketball, badminton, tennis, athletics, and pretty much any sport you can imagine.

Here’s the “magic prompt” you’ll be using:

Please create a text-to-image prompt to generate an ultra-realistic cinematic sports poster.  


General Rules:  

1. Use the uploaded photo as the reference for the athlete’s face, hair, body, and original angle.  

2. Show the athlete in **three perspectives**:  

   - A super close-up portrait wearing the official [CLUB/COUNTRY] [CURRENT YEAR] uniform.  

   - A side view. Depending on the sport:  

     • If the sport uses names and numbers → show the back of the jersey with [NAME] and [NUMBER].  

     • If the sport uses names and country/club but no number → show the back of the jersey with [NAME] and [CLUB/COUNTRY].  

     • If the sport does not use names or numbers → simply show the side view in the official uniform.  

   - A full-body shot wearing the complete [SPORT] outfit (jersey, shorts, socks, shoes, or the standard gear for the chosen sport).  

3. At the bottom of the poster, add a dynamic action scene based on [SPORT] (example: bicycle kick for football, slam dunk for basketball, smash for badminton/volleyball, forehand for tennis, javelin throw, sprint, etc.). Apply motion blur and realistic environmental effects (grass flying, sand, sparks, water splashes, etc. depending on the sport).  

4. Apply the correct text on the uniform depending on the chosen style:  

   - [NAME] + [NUMBER] (for sports like football, basketball, futsal, etc.).  

   - [NAME] + [CLUB/COUNTRY] (for sports like badminton, tennis, table tennis, etc.).  

   - Only [CLUB/COUNTRY] (for athletics, swimming, martial arts, etc.).  

5. Use a dramatic stadium or arena background suitable for [SPORT], with a cinematic and epic atmosphere.  

6. Add glowing text behind the athlete:  

   - If using [NAME] and [NUMBER], show both.  

   - If using [NAME] and [CLUB/COUNTRY], show both.  

   - If only [CLUB/COUNTRY], show the country/club or the name of the [SPORT].  

7. Place the [CLUB/COUNTRY] logo or flag in the top right corner of the poster.  

8. Overall style: **ultra-realistic, high-resolution, cinematic sports poster** with dramatic lighting and a grand atmosphere.  


Variables to be filled by the user:  

- [SPORT]  

- [NAME] (optional, if supported by the sport)  

- [NUMBER] (optional, if supported by the sport)  

- [CLUB/COUNTRY]


Now, before you use it, you’ll need to edit a few parts:

  1. Sport → For example, football.
  2. Name → If your sport uses names on the uniform, add yours. For example: Charlie. If not, skip it.
  3. Number → Add this if your sport uses jersey numbers. For football, yes—let’s say number 17.
  4. Club or Country → Add whichever applies. For example, Barcelona.

After you’ve filled those in, here’s what you do:

  1. Copy the edited prompt.
  2. Open ChatGPT.
  3. Paste the prompt and hit send.
  4. ChatGPT will give you a ready-to-use version that’s perfectly formatted for Gemini.

That’s it—you’re now armed with a prompt that can transform any picture into a sports poster masterpiece.

Step 2: Making the Sports Poster

Now comes the fun part: turning your edited prompt into an actual poster using Google Gemini’s Nano Banana feature. Don’t worry, the steps are easy, and you’ll be done in just a few clicks.

Here’s what you need to do:

  1. Copy the final prompt that ChatGPT gave you.
  2. Open Google Gemini.
  3. Choose the Nano Banana feature.
  4. Upload the photo you want to use.
  5. Paste the prompt into the box.
  6. Hit Send.
  7. Wait a few seconds while Gemini does its magic.

And boom—that’s it! Your cinematic sports poster is ready. You can download it straight to your device and show it off to your friends, share it on social media, or even print it out to hang on your wall.

I tried this with football, but I also tested it with basketball, badminton, and athletics. The results blew me away. Each sport had its own unique vibe, with action effects that matched perfectly—like sparks for basketball dunks, sand flying for athletics, or water splashes for swimming. It really feels like something you’d see in a movie poster.

Example Results

Here are a few examples of posters I made using the same magic prompt:

  1. A football poster with my name, number, and Barcelona jersey.
  2. A basketball poster showing a slam dunk with glowing stadium lights.
  3. A badminton poster featuring a smash action scene with motion blur.
  4. An athletics poster of a sprinter with sand and dust effects flying.

The variety is amazing, and the best part is you can keep experimenting. Just swap out the sport, change the name or number, or try different photos. Every time, you’ll end up with something fresh and cinematic.

It’s a fantastic way to celebrate your love for sports, surprise your friends with personalized posters, or even make cool social media content. Whether it’s football, basketball, badminton, tennis, or track and field—this method works for all of them.

So go ahead, grab a photo, fill in the variables, and let AI handle the rest. Trust me, once you see your first poster, you’ll want to make one for every sport you can think of!
