Sorry, I see my question was'nt clear enough.

Is there a way to restore all the images included in a figure library 
as jpg's, png's or what else?

I could then delete the original images.

Hi Wolfgang,

I use myself pdfimages to extract pictures from pdf-files, but it did
not always work perfect on the files I use them.

I dont know what is possible with commercial tools like Acrobat.

You should test first if you can restore your images from the picture
file before you delete them all.

in principle one could extract them but one also has to make sure that no xforms are used then, otherwise after a few cycles one ends up with many nested xforms; think of something   

\startTEXpage 
\externalfigure[yourbase.pdf][page=1,object=no]
\stopTEXpage 

another option is to use pdfimages (which can extract bitmaps); it's probably no big deal to extend rlxtools with an option do extract the images and give them their original names; maybe on a rainy day ...
