Rendering structure of PV mRNA 620 nt long with energy of -6.70 kcal/mol as calculated by RNAeval using VARNA Java applet with some IRESite improvements (see VARNA modified by IRESite). Hold left mouse button to move structure parts, hold right mouse button to move whole structure, use mouse wheel to zoom. Right mouse-click opens a menu to export into JPG/SVG and many other options.

You need a Java-enabled browser so that modified varsion of VARNA could be started. See http://www.iresite.org/VARNA/ for more details.
