Thumbs FAQ

Q: Where can I find an answer not listed here?
A: The best place to look is the Thumbs forumsClick here.

Q: Can I customize the HTML Thumbs generates?
A: Of course, just load it into any text editor or html editor and edit away.  Be aware though that if you run Thumbs again on the same folder tree it will erase your changes.  A better solution might be to create your own templates.  See the next question

Q: Can I customize the way Thumbs generates HTML?
A: Yes.  Since version 3.0 you can create templates.  Templates specify 100% of the HTML that thumbs generates. See Making Templates

Q: How is Thumbs able to not generate thumbnails for thumbnails it has already generated?
A: Thumbs assumes it's free to manage all the files inside folders called thumbs_d.  It does not generated thumbnails for images inside those folders.

Q: What file formats does Thumbs support?
A: Thumbs currently supports .JPG as read by the Intel JPEG library and .MPG as read by DirectShow in Windows and .MOV/.QT/.PNG/.PSD/.TGA/.TIF/.SGI/.RGB/.BMP files as read by Quicktime.

Q: Why are MPG files not shown in the slideshow?
A: Because there is no browser independent way to do this.

Q: Why is there no option to put the thumbnails someplace other than in the same place as the original images?
A: Because the point of Thumbs is to make something that's easy to copy to a CD or a webpage.  As it is, you can copy just one tree of folders to a CD or webpage and it will work.

If you don't want Thumbs to put the thumbnails in the same place then make a copy of your image folders and run Thumbs on the copy.


Q: How do I make my CD autorun?
A: See Making an autorunning CD

Q: How do I deal with the fact that CD filenames can only be 64 characters and yet I want to give my pictures very long names that are descriptive of the picture?  When I make a CD those names get shortened and everything stops working
A: See Shorts

Q: How do I overcome the case-sensitive problems of the web?
A: Most web servers are case-sensitive.  This means that if you have an image called "MyImage.JPG" and you have Thumbs generate thumbnails for you, by default Thumbs will not change the case of any files and will reference your file as "MyImage.JPG".

The problem is that when you upload these these images to a web server, often the case will get changed so that "MyImage.JPG" might get uploaded as "myimage.jpg" or "MYIMAGE.JPG" or "Myimage.jpg" at which point your pages will no longer work because the page will be looking for "MyImage.JPG" but it will not exist.

You have three choices,

  1. Find software that will make sure the case gets uploaded correctly.  Maybe at Tucows
  2. Tell Thumbs to rename everything lowercase

    To do this run Thumbs, click Options, click the "Build Options" tab, then check "Make Filenames all lowercase"

    Note: this option will rename all your images in place so for example "TheBigPartyPicture.JPG" will become "thebigpartypicture.jpg".  If you don't want to lose the capital letters but you still need thumbs to use all lowercase for a web site then make a copy of your image folders and run Thumbs on the copy.

    NOTE: do not use this option on non-English alphabets
  3. Use this software I wrote to fix this problem.  Shorts.
