You know you can edit your posts up to 5 minutes after posting right? Tap the little pencil icon in the upper right And it did that because you put the closing imgfit in the wrong place. you left a bunch of the url after the code
The second time you put this: Code: [/imgfit] not at the end of the full url. you put it at the end of the .gif, which makes the image work, but the url you copied also had a series of numbers following it. you either delete those numbers or put the above closing code at the end of them.
If you're not confident in your ability to post gifs correctly, >please use this test thread< rather than creating multiple threads with the same intention. Thank you! ??
