Adjust Frame width for images

Thank you for all the work on this. We're *almost*, but not fully there yet. The issue I'm having with the new frames is that the minimum width is 25. Why is this not changeable? 25 is a very thick border and, again, the image looks clunky and unprofessional. Please tell me I'm doing something wrong so I can get the classic, thin keyline that we've all been wanting and waiting for. Thank you.
