TYPO3 Core

looks like
tt_content.image.20.
imgList.override.field = image_fileUids

on line 662 of setup.txt is the cause for the problems.

/* Update, seems like also with 6.1.1 the images are added twice in sys_file repository, no matter which css_styled_content is used

However, when removing this line, the images are added again to sys_file without a repository, therefore the 4.7 css_styled_content option is not useable.

Can confirm the problem for all 6.x releases:

Seems to happen here, if FAL images are used (CssStyledContentController):

        if ($equalHeight) {
            // Initiate gifbuilder object in order to get dimensions AND calculate the imageWidth's
            $gifCreator = GeneralUtility::makeInstance('TYPO3\\CMS\\Frontend\\Imaging\\GifBuilder');
            $gifCreator->init();
            $relations_cols = array();
            // contains the individual width of all images after scaling to $equalHeight
            $imgWidths = array();
            for ($a = 0; $a < $imgCount; $a++) {
                $imgKey = $a + $imgStart;
                $imgInfo = $gifCreator->getImageDimensions($imgPath . $imgs[$imgKey]);
                // relationship between the original height and the wished height
                $rel = $imgInfo[1] / $equalHeight;
                // if relations is zero, then the addition of this value is omitted as the image is not expected to display because of some error.
                if ($rel) {
                    $imgWidths[$a] = $imgInfo[0] / $rel;
                    // counts the total width of the row with the new height taken into consideration.
                    $relations_cols[(int)floor($a / $colCount)] += $imgWidths[$a];
                }
            }
        }

$imgInfo always stays empty. Same happens if you sanitize the path for FAL. So I guess that GifBuilder can't be used to return current image dimensions. If so, this is a serious one.

This part should be completely rewritten to make use of the FAL Processing API
