import arcpy, os, simplejson as json

cwd = os.getcwd()

    data = json.load(data_file)

### Create Match Table ###
rows = arcpy.InsertCursor(cwd + '/data.gdb/MatchTable')

for cmtX in data['layers'][0]['attachments']:
    row = rows.newRow()

    row.setValue('GlobalID_Str', cmtX['parentGlobalId'])
    row.setValue('PhotoPath', cwd + '\\photos\\' + cmtX['parentGlobalId'] + '\\' + cmtX['name'])

    rows.insertRow(row)

del row
del rows
