I'm a little confused. I thought that an EPS by its nature only contained one page. But anyway, if your source contains multiple pages, you can control the output naming: convert input.ps output%03d.png
would give you output001.png output002.png etc. Ich habe 3 Jahre Deutsch in der Schule, aber ich behalten fast nichts. Sorry.
