Online image converter does not produce 24bit bmp

probably the same issue as in my offline conversion script. Will fix.

Offline script for reference:

`#!/bin/bash

filename=$(basename -- $1) filename="${filename%.}" setname=${PWD##/}

mkdir -p ../../144/$setname mkdir -p ../../288/$setname convert $1 -rotate 270 -resize 288 BMP3:../../288/$setname/$filename.bmp convert $1 -rotate 270 -resize 144 BMP3:../../144/$setname/$filename.bmp`

fixed now by writing the image buffer to disk, as the inbuilt imagemagick function ignores the fileformat set
