Hi Ian,
Do you mean the thumbnail you see in the Explorer for a file.
I tried looking in system Help.
Start, Help, search:, preview picture
Followed those directions and the thumbname area on the left became
very large so I eliminated that view.
I also tried thumbnails but that was a view of all fo the files and was taking
a long time to generate and created a database file something like
thumbs.dbx
Looks like it is a folder option but I can't find anything.
I looked in my folder and there were excel files that show thumbnails
to the left of the file names one was from someone else and one
was mine the other 30 Excel file do not show a thumbnail. I opened
both of them and saved the one I had created and lost the thumbnail.
My Excel is 2000 and my operating system is Windows 2000,
I tried opening an Excel file with Internet Explorer and it generated
a separate HTML file, which had a thumbname, but did not generate
a thumbnail for the Excel file itself.
Sorry about previous response, it was to a different question, and explains
why my response was ignored rather than just being later than everyone else's.
Also sorry about making it look like you got an answer, what version
of Excel and Operating system.
HTH,
