displays an image with other images on it
Almost every language can achieve this. Such as Python with Pillow
C++ with opencv
and many other options. (I believe most of mainstream languages will have their own image library)
The problem is, what you want to implement specifically?
if you just want to put some images on to another image, and you do not need extra interactive function. Go with Python and Pillow, it is easy to learn and can perfectly solve your problems.
