You can do this entirely on the client if
(1) you either know the names of all the image files in the directory
on the server or
(2) you can construct them programatically at runtime.
The latter works for instance if the file names are something like
image_1.png, image_2.png, image_3.png, ..., image_n.png, etc.
If you can do either of these, you just do the following in a loop,
where i is the index on the loop:
image[ i ] = new Image(); // store away the reference for later
image.onerror = function(){ /* this is my error handler */ };
image.onload = function(){ /* and I get here once the image loads
successfully */ };
image.src = urlPath + constructFileName( i ); // go get the image
urlPath would be something like 'localhost/currProject/images/', and
constructFileName( i ) either pulls the name out of a prepopulated
array, as in (1), or builds it as in (2).
You can also get the image stream directly via an $.ajax( ) call and
assign it to image.src on success:, but the above is I believe a bit
simpler.
Hope that helps,
