Reading inside PNG or SVG files isn't something screen readers can do, if
they are really reading the screen.  If they are getting part of their
information from something like MS Active Accessibility, then this might be
possible.  This is more likely to work in self-voicing browsers like Home
Page Reader, PWWebspeak, Brookestalk, etc.  But I don't think anyone is
making use of text embedded in images.
