Jpg corrupted attachments after several hours of uploads

We have problems with the jpg images attached. At one point they looked good and now they look corrupt. In our premium account

There jpg displayed overlapping with other

Other jpg are corrupt

It is verified that they rose well originally - they became corrupted later when several hours were up

here are other forms with the same problems

I tried to find the form affected, but wasn't able to. Could you please share the Form ID where you are experiencing this problem so we can investigate.

We'll wait for your response.

Thank you!
