Problem:
The website uses all GIF and JPG format images; but in IE when the same image file saved, saves the image file in .BMP format.
IE File Save As saves for all image files in .BMP format
Solution:
There are three reasons for the problem.
o There may be damaged ActiveX or Java Objects in the Download programs
section of Internet Explorer. To resolve, remove damaged objects from
Temporary Internet Files and Folders.
o The browser cache may be full and will need to be emptied. To
resolve, clear all temporary files from the Temporary Internet Files
and Folders; and free-up the cache.
o IIS has immediate Content Expiry applied on the website, which
expires immediately the HTTP header values of the page containing the
information about the image file and its format. Remove Content Expiry
from the website and apply it only on the folder which require page
expiry immediate.
