The first answer here is an informal request of a friend or colleague and the second answer is more formal and polite, perhaps if you were speaking to a superior.
'May I' is a polite way of requesting something. It cold be proceeded by the word 'Please'. e.g. 'Please may I see....'
1つ目の回答は友達や同僚のカジュアルなお願いで、2つ目は（目上の人と話すときなど）よりフォーマルで丁寧な表現です。
'May I'（～してもいいですか？）は何かをお願いする丁寧な表現です。'Please'を付けるとより丁寧になります。
'Please may I see....'
～を見てもいいですか？
Take any pictures: the word take is a verb used with pictures meaning they snapped a pictures with their camera.
Any of the two phrases can be used with friends and acquaintances.
May I is a correct form to use instead of Can I. May I is asking permission and politer.
Hope this helps!
Take any pictures（写真を撮る）: takeは、カメラで写真を撮るという意味の動詞です。
この2つのフレーズどちらも、友達や知り合いに使うことができます。
May Iとは、Can Iの正式な表現で、～してもいいですかという意味です。 May Iは、許可を求める、より丁寧な表現です。

When talking about events or places they attended or visited, some people can make it so interesting that you wish you were there. As a result, you become so interested that you would like to see pictures of the event or place they are talking about. Whether it is an event or a place that your friend is talking about, you may ask him/her as follows:
Do you have any pictures of the event? Please show me if you have them.
or
Please show me pictures of the event if you have any.
or
If you do have any pictures of the place, please show me. I would like to see them.
参加したイベントや行った場所について、自分もそこにいたかったと思わせるように上手に話す人がいますね。そのイベントの写真を見てみたいと思うかもしれません。

【訳】イベントの写真はありますか。あれば見たいです。
Please show me pictures of the event if you have any.

If someone is telling you a story of how they went swimming with the dolphins, of course you would ask to see some pictures. "I would love to see pictures of that" or "Do you have any pictures?" You do not need to repeat the specific event, but just mention "of it" or "of that" or nothing at all. This is only if you are in the middle of a conversation. Instead, if you want to see picture of a specific thing your friend did, "I would love to see pictures of when you went swimming with the dolphins!"
もし誰かに、イルカと一緒に泳いだ話をされたら、当然その時の写真を見せて欲しいとお願いすると思います。
"I would love to see pictures of that"（その写真を見たいわ）
"Do you have any pictures?"（写真持ってないの？）
具体的なイベントを繰り返す必要はありません。"of it"（それの）や "of that"（あれの）、または何も言いません。ただこれは会話中だけです。
具体的なことに言及するなら、例えば：
"I would love to see pictures of when you went swimming with the dolphins!"
（あなたがイルカと泳いだ時の写真が見たいわ！）
