Help, doubts for module creation

[Hunier]

Hi everyone, I'm having a problem, I put an image as a base for my client, but when I minimize the client it does not minimize it, in case it does not decrease, it keeps the original size, does it have any function, does it? Could someone give me a light?

What do you mean by 'image'? Please give a clear information or post a screenshot.
