ok
iam assuming IE....
heres the way...first Q, u have got the idea after the partial load of image and want to cancel further loading.....just do a ESC from keyboard and u r done...
for second Q, if u want no images to b loaded and only selected ones to b, then open Tools-->Internet Options-->Advanced-->and uncheck 'Show Pictures'...
Now right click on the empty frame of any of the pic u want to see and click 'Show Picture'...
i think u r done ....
