Hi all
I'm looking for a image upload plugin!
I'm searching something like paperclip, but thumbnails should not be stored permanently. They should be generated when they are displayed and then be able to be cached! Fleximage does something like this, but it does not allow to upload different image-formats and autodetect the file type on show-action.
Does anyone know such a plugin or have I to write it on my one? 
greets
