Which version are you using? isave was introduced in 7.1.
If you need to do it in an older version, you may see if this will
work:
http://www.ppenteado.net/idl/pp_itool_save.html
http://www.ppenteado.net/idl/pp_itool_save.pro
It was written to save isv and/or eps. But looking at the code, I
think that if you give the keyword epsfile a png file name, it will
make a PNG, because the file format is decided by the extension in the
file name. I do not know for sure because I do not have an older IDL
installed where I can check it. If you do use it and it works, let me
know and I may change the code to indicate that it can save to other
formats.

I can't find a procedure or function called isave in help --- it is
undefined at the command line.

It may be as simple as
isave,'image.png'
See the help for more details.
