Problem with a set of tiff

[luca marletta]

Hi List,
I got this problem with a set of tiff that I received.
I cannot easly open with common application (gimp and other) and made
a tileindex shp, mapserver blows off the cpu.
With an old set similar I didn't trouble.
The dimension in px of this new one is double but it seems not this the problem
I can open them in Qgis but mapserver don't like them at all.
here some info from these tiff file
