I apologize if this thread is already created but this is how to post full sized pictures in your posts.
Step 1: Bring up this screen by clicking the reply or quote buttons.
Step 2: Type your message, and then (I use facebook to upload my pictures) So go onto facebook if you have one.
NOTE: You will need to open a second tab in your browser for this
Step 3: Open a photo that you have uploaded like so;
-3a: click on Photos
-3b: Click on your photos
-3c: Select the photo you want to upload
-3d: Once you select your photo, click to open it
-3f: right click and select copy
Step 4: Click on the Jeepgarage.org tab on your browser window
Step 5: Go back to your message screen to bring up your message. Right Click on your message.
Note: Make sure you hit enter so your cursor is below your typed message, then right click, and select paste
Step 6: Once you click paste your picture(s) will be inserted into your message. The only thing left to do now is click post and your message and pictures will be displayed in all its glory. full sized and no need to open it up.
Hope this helps those wondering how to post full sized pictures!
