Chat view image help me

in my chat application when I send an image, after quitting the application and opening it again the image changes to a URL, how do I make it remain an image instead of a URL? What is wrong ?

Explain it better and upload a screenshot of your block you set :eye_in_speech_bubble:

my blok

when I sent the image it was successful, but when I exited the application the image became a url What is wrong ?
