a) The fastest way for loading images is caching them, so load them into
dynlayers at the beginning of your game, so that the browser has the image
in it's cache.. after that it will get it fast enough everytime.
Also note, that NEVER use setBgImage() to set the images in the dynlayers,
IE will reload the image everytime the layer changes (size, position,etc..)
b)
I usually just use DynLayer with setHTML to insert the image.. this is the
fastest object available (not sure how dynimage works, but since it's an
extra object it might be slower then using normal layers)
c) BMP is not possible.. My opinion when doing web-games are that your
images must be as small as possible (as little amount of colors needed, so
16 if possible), and if possible contain no transparency.. this way the
browser can handle it faster.. Also make sure the image don't contain any
extra white-space on the edges, this is just wasted time for the browser to
render the space which is not there. GIF images use RLEncoding, so white
space is still processed even though it's not there.. and since browsers are
not doing a great job of rendering, try to make everything as "easy" as
possible for the browser.
Ofcourse backgrounds can be JPG with 16million colors (as long as they don't
move) but again, areas of this background will be re-renderd by the browser
when ever something passes over them.. so use 256- color images when ever
possible.
