Clear, thank you! I didn't know about Nano Banana for this! Would be cool if they let you edit the image text directly, not sure though, I've never used that tool. Impressive that it generated that!
NB doesn't support direct editing of an image. But you can open the image in something like Krita or Photoshop, highlight the part you want to change with a red marker, and then ask Nano Banana to modify that highlighted section. It usually does a really good job.
In many cases you can just prompt “change this source text into this target text,” and it works in most cases.
