You can't preload your textures for many renders. Each render start with 
a "clean slate".
There is one exception, but it can't output to a file.

What kind of textures?

For procedural textures, you can easily compile a custom My_texture.inc 
file that only contains the texture that you actualy do use and made 
available.


If the textures are images files, try to use some compressed format and 
don't use uncompressed ones like BMP, TGA or TIF/TIFF. The decompression 
takes lots less time that loading larger, uncompressed, files from disk.

To get the files size smaller, thus faster loading, try reducing the bit 
per pixel count. High colours (16 bits) or paleted colours (256 / 16 / 8 
/ 4 colours) will give smaler files than true colours.
Increase the compression ratio as much as possible.

Use tilling if possible.
Reduce the resolution of the image and use interpolation.

Try replacing image_map with procedural textures whenever possible.
