There are a couple of ways.
1. First, this python script will extract the images to a to a folder of your choice. It is not very fast though.

fl = FeatureLayer(fl_url)
feat_set = fl.query(where='0=0')
oidFieldName = feat_set.object_id_field_name
oids = [f.attributes[oidFieldName] for f in feat_set.features]
for oid in oids:
attachments = fl.attachments.get_list(oid=oid)
if len(attachments) > 0:
for attachment in attachments:
fl.attachments.download(save_path=local_path, oid=oid, attachment_id=attachment['id'])
print(f"{attachment['name']} downloaded") folder directly from GIS platform:
1. If you have a large number of images, this is the faster way.
You can also copy the feature and attachments to a file gdb in ArcGIS Pro using the Copy Features tool, making sure to check the Include Attachments and in Environments, checking the Preserver GlobalIDs.
Then you can use this script to extract the images from there:
import arcpy
from arcpy import da
import os
inTable = r"Path to file geodatabase\YanktonTBAMultisite.gdb\Photo_FC__ATTACH"
fileLocation = r"Path to folder where images are to be extracted"
arcpy.Exists(r"verify file geodatabase existance\YanktonTBAMultisite.gdb")
with da.SearchCursor(inTable, ['DATA', 'ATT_NAME', 'ATTACHMENTID', 'REL_GLOBALID', 'GLOBALID']) as cursor:
for item in cursor:
attachment = item[0]
filenum = str(item[1])
filename = filenum
open(fileLocation + os.sep + filename, 'wb').write(attachment.tobytes())
del item
del filename
del attachment
