How can image title affect image corruption?

Recently I have had difficulty with only one of a number of gif images on my website. The image appears normal online, but if I download it with my FTP client, either it cannot be opened due to an LZW error, or else it appears completely black.  I have been experimenting, and it appears this behavior is dependent on the file name "index-title.gif".   I am mystified!  If I use a file name "indx-title.gif", the image can be uploaded and downloaded without these unwanted developments.  But a copy of the samefile, named "index-title.gif", will exhibit the symptoms which I mentioned.  Can you help me to understand/correct this?  The images in question are published at www.mauitradewinds.com/Experts   The index-title.gif file has been downloaded, causing it to become corrupted somehow, and then uploaded so you can examine it.

While the one image is wrong, the images you've posted don't bring up any errors.  It is possible that something corrupted the file in transmission though I didn't have any trouble downloading it.  If something is corrupting it because of the filename, then you will just have to use a different name until you can find the cause.

Yeah, something must be happening in the program you are using to rename the images, because I was able to rename your indx-title.gif to index-title.gif without any corruption.  See attached:

Thank you for your comments.  The image does not become corrupted upon renaming it.  Only after uploading it to my web server, and then downloading it again, it is corrupted.  I don't mind using a different name for the image.  I would just like to understand how the name can make that difference.

Does it happen every time you download it under that name?

To me it is obvious that on your webserver you have a programming platform that uses index as a reserved word.  Anytime you use reserved words for your applications outside of their intended use you will run into problems.

Yes, it happens every time I download the file under that name.  If "index" is a reserved word, I see how that could account for the problem.  I think I will just use a different file name.  That will require some editing of the pages which link to that file, but not too much work.  Thanks to all of you.
