I spent a little over an hour last night adding a few extra features..

• Set a default thumbnail and/or image width and/or height per gallery
• Set a thumbnail and/or image width and/or height per item in the gallery (overrides default)
• Made each image go inside a wrapper, which gives more flexibility with styling in CSS (this is currently only partially implemented)

I put the changes on a memory stick so that I could upload it from work.

Turns out the memory stick is corrupted

You have a backup of them though, right?

I certainly do

This is done now. The latest version is gallery6 and the code is available on www.webtagr.com/projects - it will become a part of a few websites and also might be used on webtagr.
