The same way you just found them to upload them here..

 

1. Go to your home folder
2. press CTRL + h
3. search for your .minecraft folder

 

once you find your .minecraft, go to the screenshots folder in there, then upload it to imgur.com, then give us the link/url.

 

Okay.. let's try the forum. Right beside "Post Reply", click "Upload a File". Select the pictures you want to upload then post it.

 

All you have to do is post the link bro. Dont need all the fancy hyperlink stuff.

 

Sorry for posting but I think this might help.
Step 1: find the screenshots in your .minecraft folder (search using %appdata%)
Step 2: drag the pictures on to your desktop
Step 3: go to www.imgur.com
Step 4: upload the pics from your desktop in the upper right
Step 5: post the link to the pictures below
again sorry for posting

 

using windows 8:

1. move mouse to extreme bottom left of window, right click.
2. click run, and type %appdata%, then hit enter
3. open the .minecraft folder then proceed to the screenshots folder.
4. open web browser and go to your favorite free image hosting website.
5. upload any and all photos, copying the HTML code for hypertext, or the direct link for image insertion methods.
6. bring up this page and post pictures in ''evidence'' section, feel free to edit first post in thread.


using windows 7 & vista:

1. click start menu and open 'my computer'
2. from there navigate c:/ > program files or program files x86 > look for minecraft
3. If not found there, return to the start menu and click run.
4. type in %appdata% and hit enter
5. refer back to #3 in the windows 8 directions.

hopefully this is clear for you, especially if you have windows 8, as i had to go through several sources before i figured out where the .minecraft folder was located :p
