Some pictures need help after upgrade

Anyone know how to fix these pictures.

One fall-back option is to install free prestools.com software in your back office directory, so the login is 
example.com/backofficename/prestoolsuitename/login1.php with default user and pass in one of prestools text files
in prestools >
images > regenerate ... sometimes works when other methods fail. I don't know why this worked for me, but it did.

regenerated and seems good so far.

 

Thanks
