image plugin

Has anyone an idea to replace this plug-in as its jpeg compression ratio is fixed and too high for me. it makes tiny images but the quality is not suitable in all situations.
I use a bean to render pdf files which is providing rather good quality images as buffered images but I still need getImage to store and display them in-from a media field. And unless there is nothing to do on them, no rotate, no resize, the compression effect is too important. Same effect when loading a jpeg image from disk, a simple 90degrees rotation makes it a lot worst.
A tool using something else than jpg images can also do the job provided it uses a format Servoy can display, png, what else…
