Hi Andrea, how did you load these rasters? Every raster in a layer (so you have actually 200 layers)? Or did you generate a tileindex file using gdaltindex and are you serving the rasterimages using mapserver?
If the first: it's fun to write a simple python plugin for that, if needed I can give you some help (thinking about: get mouseXY, walk through all layers and check if you are within the bbox of current layer, spit the layername or some other attribute name to std-out (or more fancy: show a dialog).) If the second: as Tim told you: add the indexfile as layer. You can also use that indexfile to serve the rasters via Mapserver then. Building the indexfile and just loading that in Qgis is probably the fastest way.
