-------------------------
#1 is the original sentence. What about the others? Are the others the same in meaning? Would you check them, please? Does 'it' refer to 'her photo with a lot of comments'?

1 and 3 are best. All the rest are wordy or incorrect.

In 4 and 5, the pronoun "it" seems to be referring to the photo (singular), not the the comments (plural).

Let's analyze each sentence to determine their meaning:

1. "She found her photo with a lot of comments, making fun of her pose."
In this sentence, the participle phrase "making fun of her pose" modifies the noun "comments". It means that the comments were making fun of her pose. No, "it" does not refer to "her photo with a lot of comments" in this sentence.

2. "She found her photo with a lot of comments, which were making fun of her pose."
In this sentence, the relative pronoun "which" introduces a relative clause that modifies the noun "comments". The comments were making fun of her pose. This sentence has a similar meaning as the original sentence.

3. "She found her photo with a lot of comments, which made fun of her pose."
This sentence is similar to sentence #2 but in the past tense. The relative clause "which made fun of her pose" modifies the noun "comments".

4. "She found her photo with a lot of comments, and it were making fun of her pose."
This sentence is grammatically incorrect. The verb "were" does not agree with the subject "it". It should be "it was" instead. Additionally, using "it" suggests that the comments were the ones making fun of her pose, which is not the intended meaning.

5. "She found her photo with a lot of comments, and it made fun of her pose."
This sentence introduces a compound sentence structure, with two separate clauses connected by "and". The first clause is "She found her photo with a lot of comments" and the second clause is "it made fun of her pose." In this sentence, "it" refers to the photo with comments, and the photo is the one making fun of her pose.

So, sentences #2 and #3 have a similar meaning to the original sentence, while sentence #5 is also similar but introduces a compound structure. Sentence #4 is grammatically incorrect and conveys a different meaning.
