thumbnails resizing

I have several copies of the module on one single page and sometimes, the same article will display in two of them (e.g. once in the "Latest News" [large thumb] module and once in the "Interviews" module [small thumb]). The problem is that they are both formatted rather differently, in particular the thumbnail size. However, the thumbnail seems to be stored as one single picture and will therefore display on both modules in the same way as either the small or bigger version, but not both. Is there a way to tell the component to create one thumb for each copy of the module?
I could of course set one module to display the first article picture and the other, the intro image but perhaps there is an easier way to proceed?
Thanks a lot

I think I have found the issue. I had the same ID written for the various modules. Now I have corrected it, it seems fine.
