Hi Juanjo,
I was recently in a similar situation writing a macro to open multiplei image file formats and did not want to have to rely on extensions.  However, as explained by Curtis Rueden, there are only a few formats that declare their identities their headers.  As far as file type support by ImageJ, using the Bio-formats library directly or through the LOCI plugin greatly expands the number of formats that can be opened.  If you have a few specific types of interest, you might be able to parse distinguishing characteristics in the header or metadata, but that might also be cumbersome.  

Good luck,
Glen
