How to replace the image in the program?

Question

Qt

The task is to replace the picture on an already packed program, the only thing I know is that it is written in C ++ with QT runtime.

I remember in the year 12 I often met programs that allowed me to immediately find all possible assets and also replace them.

Good, I understand correctly that the program is already fully packed, all resources, pictures inside the exe. I don’t really understand this yet, but I think the pictures can be extracted and replaced only if they are stored inside the binary file in an unencrypted form. Those. theoretically, you can try to search in a binary file for markers of the beginning of jpg files like [FF D8], determine their size, then try to replace them. Well, or there seems to be some kind of GetImage program, which, oddly enough, the search finds on the site of motofans. It became very interesting, I will also try to collect some kind of executable with a picture and try to stupidly replace the hex editor with a picture)
