Can i use size converter for thumbnail not ImageMagick?
and not all of them in list, but other more easy to install?
and can you tell me is there in you software this function?
so users can upload different sizes foto, and i set only one size for all,
and all fotos will show in this size??

Yes, GD or NetPBM

You need root acces to your server to install all convert programms. Ask your host about that...

so users can upload different sizes foto, and i set only one size for all,
and all fotos will show in this size??

At  the moment this is not possible.
