Searching for Images

I am sure we all have had that one image we remember seeing before but don’t seem to be able to quite find. Let us see if we can describe them here and the power of the human search engine can do something for us.
 
 
Let me begin:
 
Long way back then, there was this comic uploaded by accident into Ponibooru which showed Spitfire with a bandaged wing and with her face covered as to protect against sandstorms. I want to know if anyone has the picture and if you know what happened to the project related to it.

You mean this?

@hahuji  
Yep, that’s the one.
 
Now, I just need someone whom got the file on and I can continue on my search.
 
Thanks.
 
So yeah, what image do you remember but have no idea where it went?

Hi, everypony
 
I am looking for a one page comic that is about Shining Armor wants to introduce his little sister to his colleague, then Vinyl Scratch shows up and the guy thinks wrongly she is Shining’s little sister. Then Shining explains she isn’t, but that guy does not believe it.
 
Can someone help me to find it?

Oh,come on! Don’t tell me I was the only one who saw that comic.

It seems you might have been.

Can anyone please find me that comic where Fluttershy is scared on her bed listening to birds singing profanity?
 
EDIT: Nevermind.  

I’m trying to find a comic strip where every Mane 6 pony dresses up as AJ for Nightmare Night.
