Remark : an -lossless option for imagemagick can be used for to solve this 
point. But i think it's not important...

You have missing a big difference between JPEGLOssLess plugin and batch 
plugin : the first one can be operate only on the current ablum, the second 
can be operate on a list on files from differents albums. 

Also, for the plugins results : 
JpegLossLess -> source = target.
Batch -> source != || == target.

Not really redondante for the reasons above. But it's certainly confuse. A way 
for to solve that is a full documentation for this plugins.

Nota : i have provide a full 'what's this' info on batch  plugins.

If you have a best option name...

Because ihave planed some new tools in this submenu like find aproximate 
images (like ImgSeek !), find comments, etc.
