Some pictures are lost when exporting chat

[blastrock]

Steps to reproduce

1. Post a lot of picture all at once in a chat
2. Export the chat

Outcome

What did you expect?

The export should contain all the pictures

What happened instead?

Images are named with a date-time, like image-7-30-2024 at 4-22-57 PM.jpg. So if two images are posted within the same second, only the first one will be saved. This happened to me when a friend posted a lot of photos on WhatsApp, all the messages were received in the same second.

Marking this a good first issue as it should be fairly straightforward to just append (1), (2) etc to images whose name would end up the same... that or just a few random characters.
