Auto Resize of Pop Up has changed all images

[Confused Sally]

I used the Advanced User Guide to put code into the extended pop up window to auto resize it to the image.
When I tried to upload I got the following message
'A page named 'C:\Program Files\Actinic v8\Sites\Site1\SiteHTML\' has already been generated for the extended info page 'Little Blessings Motifs on Turquoise'. The same page name is used for the extended info page 'Little Blessings Daisies on Yellow' and therefore the previously created page will be overwritten.

Do you wish to continue the upload?'

I tried to see what would happen but it became obvious that every product with an extended info page was affected and about to be overwritten.
I have now removed the code and it seems to have put everything back the way it was before. However I would really like the ability to auto resize the window - any ideas how to sort this out?
Thanks for any help

I used the Advanced User Guide...

It would help if you can link to the exact article you are using. Otherwise you are asking people to hunt around and/or guess what code you are using.
