Not really. Bitcoin blocks are limited in size, originally to 1MB, now the limit is a bit fuzzy but the largest theoretical block is 4 MB. Transaction fees are (again, fuzzily) paid by transaction size, so if someone wanted to fill a block with a large transaction that contained a file they would have to pay an equally large fee.
Furthermore, the protocol is designed to find new blocks every 10 minutes. The actual rate is up to chance. Sometimes several blocks can be mined in quick succession, other times blocks may need 30+ minutes. But over the long term, the protocol ensures blocks are found every 10 minutes. Once the transaction is accepted into a block and that block propagated, it will be made immutable and the time of block creation will be fixed y multiple distributed mining nodex (assuming the block continues to remain in the longest chain, which it likely will be).
But even then, what do you have? All you have is proof that a file existed at a particular time. It says nothing about its provenance. If you want to vouch for the authenticity of a file on social media, you are much better off just posting a hash of the file, preferably signed with a known GPG key. I mean, that is basically what the Blockchain is doing, just with transactions attached.
It’s all very confusing but apparently you can inscribe image data(even video) directly into individual satoshis creating permanent artifacts that live in the blockchain itself. I think there are multiple methods.

Bitcoin itself has a new technology called ordinals that use decentralized storage and hashing to preserve image data and provenance.
I don’t think Ordinals really help here, they just turn Bitcoin into 2.1 quadrillion individual NFTs. But, my knowledge may be dated.
