i'm learning opengl , used soil lib map texture(png file) quad (follow nehe tutorials).nehe used image size 256x256. can use smaller picture ?(any size or power of 2 size) ? load texture function:

int loadgltextures()                                     {       texture[0] = soil_load_ogl_texture         (         "nehe.png",        soil_load_auto,         soil_create_new_id, soil_flag_mipmaps | soil_flag_invert_y | soil_flag_ntsc_safe_rgb | soil_flag_compress_to_dxt |soil_flag_power_of_two          );      if(texture[0] == 0)         return false;      //glgentextures(1, &texture[0]);     glbindtexture(gl_texture_2d, texture[0]);     gltexparameteri(gl_texture_2d,gl_texture_min_filter,gl_linear);     gltexparameteri(gl_texture_2d,gl_texture_mag_filter,gl_linear);       return true;                                        // return success }
