By "force resize", do you mean declaring their width and height in the IMG
tag? If so, be aware that you aren't saving any loading time or bandwidth;
the full size image is downloaded and rendered at the client end, just
smaller. You'll probably find that the "full" size image loads near
instantly as it's just a local cache of the thumbnail.

A single page can refer to any number of images/sounds/flash
animations/stylesheets/js include/etc/ on any number of disparate servers.
But measuring the performance of each isn't something you can do with much
accuracy in the way you suggest; the speed of response will be sensitively
dependent on;
* Client browser configuration: number of simultaneous connections,
caching and security policies, local firewall settings etc. etc.
* Intervening network settings: proxy settings, DNS performance, number of
transparent caching proxies between the host and the client
* Network conditions: bandwidth at each hop, traffic and reliability
* A million other things
In short, testing this sort of thing and getting meaningful results is
difficult and time consuming, even when (no offence) you know what you're
doing.
Continue by all means, you'll learn a lot, but if all you're interested in
is reliably hosting images, look for a popular host that people *pay* for.
If they can make money doing it, evolutionary and market forces
practically guarantee it's worth paying for.
