You are not alone. Microsoft has a support file discussing this
problem:
SYMPTOMS
When you use the Save Picture As command for a graphics file in
Internet Explorer, you may be able to save the file only as a BMP
file, even if the file is in another format (such as GIF or JPEG). The
file name may also appear as "Untitled."
CAUSE
There are several reasons why this issue may occur.
This issue may occur if your Temporary Internet pages cache is full.
This issue can occur if you have "Do not save encrypted pages to disk"
selected in Tools, Options, Advanced Tab and are loading the page over
a secure connection (https).
This issue can occur when you connect to a Web site using an address
that contains <username:password>. For example, the server is accessed
through http://<username:password@site>/default.htm, instead of
http://<site>/default.htm.

Image with Correct Extension
WORKAROUND
You can use any one of three methods to work around this issue.
Workaround for Cause 1
To resolve, delete the temporary internet files by selecting Tools,
Options, General tab and select the Delete Files button.
NOTE: To locate the Temporary Internet Files folder, click Options on
the Tools menu, click the General tab, and then click Settings. The
current location is indicated in the Settings dialog box.
Workaround for Cause 2
To workaround, uncheck "Do not save encrypted pages to disk" from
Tools, Options, Advanced Tab. Then select View, Refresh to reload the
page.
Workaround for Cause 3
Method 1
Open the Temporary Internet Files directory and locate the image that
you attempted to save.
Right click the image and click Open.
When the image loads into Internet Explorer, right click the image and
click Save Picture As. The correct file type and name should be
correct.
Method 2
Type in the direct path to the image that you wish to save.
When the image loads into Internet Explorer, right click the image and
select Save Picture As. The correct file type and name should be
correct.
Method 3
You can also save the file in .bmp format, and then use a graphics
editor to convert the file to the desired file format.

--------------------------------------------------
In my experience, the most common cause for this problem is 'Cause 1'
listed above, related to your Temporary Internet Files. Usually
deleting your temp files (as directed in 'Workaround for Cause 1'
above) will solve the problem, and increasing the size of your temp
folder (in 'Options') will help keep the problem from returning.
My Google search strategy:
"explorer" + "save" + "graphics" + "files" + "format"
