If what we want to do is to alert users, we could use this: 

"Image "D:/Git_New/my_fgdata/Textures/Terrain/sand6.dds" uses compressed
textures which may be unsupported by your system and may not display
properly." 

 Such a message could be displayed on the splash screen of individual models
rather then as alert, on the assumption that the many users never see the
console which is hidden behind the fgrun window.

On the other hand, if you are trying to tell aircraft modelers not to use
these forms (.dds .ivs) of compression, then:

"Image "D:/Git_New/my_fgdata/Textures/Terrain/sand6.dds" uses compressed
textures which may be unsupported some systems. To remove this alert,
decompress this texture."

My concern with the latter form is that it only applies to very limited
number of aircraft models and developers, while it is at best meaningless to
the user, and may lead to confusion.
