 How To Fix The 'Save As' Option in I.E.
Have you ever had or have a situation where when you right click an image in I.E you can only save it as a BMP?
For whatever reason, Windows defaults to BMP when your cache is full and will only allow you to save the image as a bitmap.
This really makes no sense because bitmaps are usually much larger than JPGs or GIFs. Be that as it may, you cannot save images in their correct format until you clear your browser's cache.
To clear your cache manually follow the instructions below assuming you're using Internet Explorer 6:
Under the Tools menu at the top of your browser, select Internet Options.
Click the General tab.
In the Temporary Internet files section of the General tab, click the Delete files button.
A dialog box will appear that says, “Delete all files in the Temporary Internet Files folder?” Click the OK button.
In the History section of the General tab, click the Clear History button. A dialog box will appear that says, “Are you sure you want Windows to delete your history of visited Web sites?”
Click the YES button.
Click OK to leave Internet Options.
Click the Refresh button at the top of the browser |
