Comment (by kuscsikp):

 It is a bmp image with 8000x8000 size. But, only the first 40 Kbytes are
 there, some megabytes from the end of the file are cut down. Sending this
 file is fast (only 40 kbytes to send), but processing  or displaying it
 needs a large amount of memory(64x3 megabytes) and time. Similar problems
 are at the firefox:

 Try to open this in a firefox browser.
