How to export multiple MXDs to PNG without using VBA?

Question

Okay, so I can feel that I am so close to solving this issue with the help of Jason (below) but I have modified to use as a script. The GetParameterAsText returns the following error when trying to execute:

: [Error 3] The system cannot find the path specified: u"'C:\Users\bob\Documents\folder\file.mxd';'C:\Users\folder\Documents\Folder\file.mxd';'C:\Users\folder\Documents\folder\file.mxd'\*.*"

Anyone know what is wrong with my code to keep getting this error?

 import arcpy, os, string
 #Read input/output folder path from script tool
 folderPath = arcpy.GetParameterAsText(0)
 outPNGfolder = arcpy.GetParameterAsText(1)
 for filename in os.listdir(folderPath):
 fullpath = os.path.join(folderPath, filename)
 if os.path.isfile(fullpath):
 basename, extension = os.path.splitext(fullpath)
 if extension.lower() == ".mxd":
 mxd = arcpy.mapping.MapDocument(fullpath)
 arcpy.mapping.ExportToPNG(mxd, basename + '.png')

• klewis: What is "mapping.PNGDcoumentCreate(outPNGpath)? This isn't a real mapping function. You don't need this line. You can download Pyscripter (free) and learn to debug your script.
• newbie123: I was trying to modify an existing script that batch converts multiple map documents into a single PDF. I am new to all of this but couldn't find a simple solution to batch export multiple mxds into pngs thru model builder so I naturally migrated to python. I will look into pyscripter. Thank you.
• klewis: The ESRI online help has nice examples on how to use various arcpy.mapping functions & classes. help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//…
• Tom: What are you passing as your parameters? It should just be a single directory path.
• Jakub Sisak GeoGraphics: @Tom - can you please make that an answer.

From Jeff Moulds (ESRI) originally for pdf export here's some python you can customize. It works on all mxds in a folder so you could adjust that or perhaps copy the projects into one temporarily for exporting. I added paragraph spaces after the first 3 lines to make the text properly indent in the box below, not being smart enough to do that any other way.

import arcpy, os
folderPath = r"C:\Project"
for filename in os.listdir(folderPath):
 fullpath = os.path.join(folderPath, filename)
 if os.path.isfile(fullpath):
 basename, extension = os.path.splitext(fullpath)
 if extension.lower() == ".mxd":
 mxd = arcpy.mapping.MapDocument(fullpath)
 arcpy.mapping.ExportToPNG(mxd, basename + '.png')
