[Seaside] Howto Image (picture) instance variable of the class

[Oswall Verny Arguedas C.]

I understand,  I have to create a collection of internal addresses of the
images and they are saved in the system (folder).
After saving it, it must be presented on the screen.
The library to implement that is FileLibrary or there is another.
Thanks.
