Nevermind, it took some searching but I finally found the line of code to change.

Thanks for the reply, I just have a clarification regarding #2:

I didn’t mean “upload image” button… I must have been half asleep.

What I meant to ask was, how to I change the default size of the uploaded images that are uploaded from the frontend through the upload image button? When the image is uploaded into the post it uploads as a small version of the picture that was originally uploaded. I would like it to upload into the post as its full size.

Thanks.
