I am trying to run a script that generates a number of down sampled images from source images in a given folder.  I am using the Python Imaging Library (PIL) for this and the code appears to crash on the line where the output image is saved.  I have put a try/catch statement in to get more information but the process appears to crash so it doesn't even get to the error message.  The code looks like the following: import os, glob, arcpy import Image pth = arcpy.GetParameterAsText(0) sep = arcpy.GetParameterAsText(1) extarr = sep.split(".") ext = extarr[len(extarr)-1] sze_w = arcpy.GetParameterAsText(2) sze_h = arcpy.GetParameterAsText(3) arcpy.AddMessage("Got arguments!") for (root, dirs, files) in os.walk(pth):      for fle in files:          if fle.endswith(ext):              fullfle = os.path.join(root,fle)              img = Image.open(fullfle) ##             img.MAXBLOCK = 1024*1024              size = sze_w,sze_h              img.thumbnail(size, Image.ANTIALIAS)              oset = -1 * len(sep)              f = fle[:oset]              fullf = os.path.join(root, f + ".thumbnail.jpg") ##             arcpy.AddMessage(fullf + " created!")              try:                   img.save(fullf, "PNG")              except Exception as e:                   arcpy.AddMessage(e)                                arcpy.AddMessage(fullf + " created!") ##             #print fullf + " created!"              del img I should also mention that the code works just fine when run from the Python command line.  Does anyone have any ideas why this is happening?

I am trying to use create a web map that has a VETiledLayer and two ArcGISDynamicMapServiceLayers which I am able to create but now have some scale dependency issues.  I can get the map services to display correctly on loading but when I try to zoom in all the data disappears as if there was some scale dependency limiting viewing.  It appears to work when I zoom out though.  I have quadruple checked my MXD file and it now has no scale dependency applied to any of the four layers (removed to test).  Even when it did set scale dependency, I tried setting them quite wide (1:200 - 1:200,000,000).  I have tried using the MSD and MXD files for this with no luck.  Can anyone give me some direction on where to look next.
