Just TYPO3 things:

in your config constants doing "styles.content.textmedia.maxWInText = 450" should basically crop all your images to a maximum width of 450 using ImageMagick except TYPO3 flips it's shit and won't do it.

After about an hour or so of debugging and guessing around with 2 other developers setting "styles.content.textmedia.maxWInText" to "500" will actually work. Every other number except 450 works.

Using TYPO3 is like preparing for hell.
