"Could not get image size from" please Help!


Everytime i upload my csv with content, i get this error on some Product Pictures. No matter how many times i convert them it still remains even tho it’s another picture. Only renaming the Picture solves the problem but we need the reason.
Also when the picture has this error the article does’nt work in the frontend it occurs in an error for all of the variants.

Does anyone know how to fix this?
greetings
