It's hard to imagine what you did, as there are different options to do 
a HTML export.

You exported it via File - Wizards - Web Page, I assume?
When exporting it via File - Export ... choosing "XHTML" format there is 
no preview.

As we can't see what you have created, is there a chance to get a 

I can just imagine, what you want to achieve:

The present wizard creates a list of files (in index.html) as well as a 
table of contents (in /content/<filename>/<filename>.html) for 
presentations, direct preview for text files and drawings.

If the wizard was used to create a framed website (third step of the 
wizard, second line of layouts), the ToC is shown in the frame on the 
index.html page.

This ToC shows the name of the slides and a link to start a web 
representation of the file (/content/<filename>/siframes.html)

This webpage contains on the left hand side the titles of the slides 
(expandable to lower hierarchies), on the right hand side the slides are 
shown - switchable on forward/backward buttons or by clicking on the titles.

Do you want to replace these titles on siframes.html by the thumbnails 
(similar to the Slides area in Impress)?

Or should already the Table of Contents (<filename>.html) provide the 

Clickable thumbnails would be intuitive to use, providing an easy access 
to the content.

I'm sure it can be improved, especially for accessibility (selection 
movable by mouse and keyboard, alternative titles etc), but if I 
understand it right, your patch will be an improvement over the present 
state, so please go on!

You mean the "Documents" page? Under "Export to file format" a checkbox: 
"Provide thumbnails"?

In this case I agree: Even with larger presentations the size of the 
thumbnails don't enlarge the resulting website too much, but provide 
relevant information.

Thus I think we should not add an option to skip the creation of thumbnails.

(If users will complain about the resulting size, an additional option 
in "Export to file format" can be created later: "HTML without thumbnails")

I don't like these "colorful" graphical webdesign either.

I don't know how we can get better design integrated in this wizard.

Do you need color and size definition, graphics or finalized websites?

If we can get such information, we can add some kind of "Design Easy 
Hack" to work on by some interested designers.

But more important: If you leave the original file formats, you'll get 
StarOffice file icons!

These should definitely be replaced by the corresponding LibO icons.

Best regards
