Photos No Longer Showing Up

[SKB_Hamsters]

I was just browsing through a couple of my past threads and I noticed that the photos I had previously posted are no longer showing up in the threads, but the other day they were showing up fine . Is there a reason why they are no longer visible? have they been removed? Or if it just myself who can't see them?
As the post don't say they have been edited from anyone apart from myself when I edited the post.

My threads in which the photos are no longer visible are:
MY DIY Bucket Wheel
DIY Cardboard Tube Flower

If someone is aware of the reason for this could you please let me know.
