Why Has my post been voted down when I am only trying to help the guy so he doesn't buy some tablet that can't work with the images you need ?

make sure that the tablet is able to produce images/models in the right format

I presume this is because your post seems invalid and nonsensical.
The tablet computer is just a general purpose computer. They run Windows 7, or iOS, or Android. There are many great drawing apps for each platform.
It is up to the drawing program, and not the computer itself, to determine the file format. The major file formats are supported by all the significant art programs. Tablets may be a Windows 7 pc, or use iOS or Android, but all of them have drawing programs that use standard formats.
It seems like your post is declaring: "Make sure you choose a CPU that supports jpeg!" Perhaps the best result you can expect from such a declaration is that people will roll their eyes and ignore it.
