I've tried searching at Users>user>AppData>Roaming>Skype>user>Pictures but it is empty. I'm using the classic version of Skype on Windows 7.
Under "Change your photo", click Upload a new photo, and then browse to find and select the image file you want to use. I've been struggling to find out where is the file of my current Skype profile located in my computer. In the window that opens, click the picture icon ( Add or change your picture) to the left of your name. In the top right corner, click the picture icon ( Account manager). (Do not click anything on the sign-in pages other than Next and Sign in.) When prompted, confirm your identity with Two-Step Login (Duo), and then choose whether to stay signed into your Microsoft 365 account. If you see a "Sign in" prompt, enter your IU username followed by (do this no matter what your email address is), and then, at the password prompt, enter your IU passphrase. Other users also may have to sign out and sign in again to see your new picture. To see your new picture in Microsoft Teams, you may need to sign out and then sign back in. On Android devices, it’s called Ultra shot HDR.
Open your phone’s camera settings and ensure HDR is turned on. Adjusting the camera setting is another way to avoid taking low-quality images that turn out blurry as profile pictures.
After you modify your picture, it may take up to 24 hours for the change to appear in all applications. Method 2: Adjust Camera Settings on Your Phone.
