Thumbnails are wrong force caching

I used two different modules which show equal materials (and so equal thumbnails). NSP5 creating just one thumbnail for all modules, so it looks ugly on second and next modules. I'll suggest fix it by creating different thumbnails for each module (split them by module ID: first module creating his own thumbnails, second module creating his own thumbnails, and etc.)

Hi

It does that already. Please tell me the url to pages with examples. I'll see what is wrong.
