- paste the raw image data into the field 'input' (e.g. select 'upload' and then select the image to upload - or select 'from URL' and enter the image address)
- optionally you can enter a file name in the field 'dlfilename' (this makes sense if the data is binary data)
- make sure the transfer method is set to 'post'
