[Seaside] slow picture loading

[Tudor Girba]

Hi Paul, hi James,

Thanks for the answers.

I also thought it has to do with the Apache config, but I had no idea what
to look for. Your suggestion certainly look interesting to look into, but I
have close to no clue of how to do it. Do you happen to have a bit more
hands-on pointers for how to:
- increase the resources count
- add expire headers for the images

?

Cheers,
Doru
