Resample images

I know this is general purpose allowing uploading many file types, but for images it would be great if FileUpload could have a setting to re-sample images to conform to a configured maximum X & Y dimensions while maintaining aspect ratio.

Yes, it would be great !

Yes, i think so too. It would also nice to have a lightbox to view the images.

Tim has said that in the next version of FileUpload, this feature will be added... but here is a very naive way to make this work in the mean time (if you have GD php module):

Using FileUpload 1.4.0, in the class.fileupload.plugin.php after the PostController_Upload_Create function checks for $maxUploadSize on lines 597 - 601, add the following to resize the temp file before it is moved:

// Added to auto re-size images over 650px x 650px
        $FileParams = getimagesize($FileTemp);
        if ( ($FileParams[0] > 650) ||  ($FileParams[1] > 650) ) {
                include_once('/EDIT/THIS/PATH/TO/SimpleImage.php');
                $resizedImage = new SimpleImage();
                $resizedImage->load($FileTemp);
                if ($FileParams[0] >= $FileParams[1]) {
                        $resizedImage->resizeToWidth(650);
                } else {
                        $resizedImage->resizeToHeight(650);
                }
                $resizedImage->save($FileTemp);
                $FileSize = filesize($FileTemp);
        }
//end add

...then save this image resize class* somewhere (I put it in the same dir as the class.fileupload.plugin.php in the FileUpload plugin).

In this case, it checks for images larger than 650px x 650px and resizes them... you could, obviously, be more creative, but I had very simple requirements.

*Props to Simon Jarvis for his gift of a neat and simple php image resize class.
