Let’s tell you how to create Christmas greetings by generating a group image from separate photos. For this we are going to use artificial intelligencespecifically Gemini with its Nano Banana, being possibly the best free alternative to do this.
Here, the secret is again to use an appropriate prompt in which you describe exactly what you want. We are going to tell you everything you should take into account and the prompt you should use later to create the image. You will see that it is quite simple.
Group Christmas greeting with Gemini
Before you start, you first have to Carefully select the photos you want to use. Try to have similar lighting, or that the same part of everyone’s body can be seen. Gemini is going to try to cut and paste all the photos together making as little modifications as possible, so keep that in mind. They should be photos that look similar.
Of course, you should also know that you will be able to change their clothes to the people in the photos. Therefore, and although the ideal is for everyone to be dressed similarly, it is not essential, because then you can have Gemini put the clothes you want on them.


Once you have everything, start a conversation with Gemini. Inside, first upload the photos you are going to use. Afterwards, you can copy and paste the following prompt and send it along with the photos:
I want you to create a Christmas card with a family photo. I’m going to give you separate photos of people, and I want you to create a family photo where they all appear together. Under the photo you have to say “Merry Christmas”. Make the background with Christmas motifs.
In this prompt you can make changes or more details. You can describe the background to be used, and also the font and text. Don’t be afraid to try, experiment and try again if the first result doesn’t work out for you.


After doing so, as we have told you before, you can ask Gemini to change their clothes. This way, if people’s clothes are different in the photos, you can unify the result a little.
In fact, if you have a group photo you can also simply ask them to change their outfits. Another option is to upload the group photo and then an individual photo of another person who is not there and ask Gemini to add this person.
And do you remember when we told you how to turn your photos into video game scenarios either in a character from Stranger Things? Well, you can also use these tricks here to make the greeting as original and personalized as possible.
