A Somewhat Extensive Guide to BBCodes

I read through the entire thread, if I somehow missed this, I apologize for the repeat. Is there a way to show a screenshot without actually to uploading it onto a site? I noticed the image BBCode is focused on URL. This will be very useful to me when I'm making reports and a screenshot is needed if I don't need to upload the screenshot. I don't use sites like TinyPic, and I don't want to upload it on other sites such as FurAffinity.(It's like deviantArt except for furries if anyone doesn't know what this site is) If you can do this, but does not fit in the BBCodes, I do apologize for asking this in the wrong thread.

No, you can't show a picture without uploading it, although you could always use PFQ's uploader (quick access through the "Useful Links" in the announcements bar) if you want to upload something without having to use another site. Otherwise, you won't be able to use images in posts, etc.

Is there a code for a table which could have a header at the top and left?

I'm not sure what you mean. Like this?

Title
Cell 1	Cell 2	Cell 3

Sorry I don't really know what you mean, so if you clarified I might be able to answer.

I think it was more something like this:

Header
Header 1	cell 1	cell 2	cell 3
Header 1	cell 4	cell 5	cell 6

(at least it has a header at the top and the left side)

Kinda like Uzumi said XD. I had written out so much code...and then I get sniped XD.

[th] is exactly the same as [td] and can be used in the same places, but [th] will just be bolded / colored / centered.

x
x	x	x
x	x	x
x	x	x
x	x	x
x	x	x
x	x	x

So yeah, any places you can have normal cells can also have header cells. (I hope that makes sense haha.)

Yeah, that helps ^-^. Thanks!

I believe it is [you][/you] do display the viewers username?

As you see, it isn't. Also the code to display ones username is a secret~
