I'm pulling pictures from a gallery post. The goal is selecting the url that has picture size 365 x 320

if I run this code I can see all available sizes.

post_id = 'wknagi'
submission = cli.submission(id=post_id)
image_dict = submission.media_metadata
for image_item in image_dict.values():
    print(image_dict)

but for the life of me can't figure out this part from this code which gets a 3500 X

This is the code I'm currently working with

post_id = 'wknagi'
post = cli.submission(id=post_id)
gallery = []
ids = [i['media_id'] for i in post.gallery_data['items']]
for id in ids:
    url = post.media_metadata[id]['p'][0]['u']
    url = url.split("?")[0].replace("preview", "i")
    gallery.append(url)

for img in gallery:
    print(img)

I assume the variable for pic size is the ['p'][0]['u'] but I just can't seem to get 365 x 320 size.

Help! lol
