I see the problem.
std.filepicker.list1.xsl is looking for a "/root/params/image_width" instead of "/root/params/imagewidth"
With this patch, the thumbnails in the filepicker screen will properly respond to the values in the screen structure file:diff --git a/xsl/std.filepicker.list1.xsl b/xsl/std.filepicker.list1.xsl
index 320a20d..a14094a 100644

I would still like to have the images be scaled proportionally to fit into a bounding box specified by imagewidth and imageheight. Based on my reading of your code, it would have to be implemented something like this:
- std.filepicker1.inc will perform additional processing on the files it reads, based on their type.
- For images, the width and height will be extracted with getimagesize($file)
- For other files... some other relevant metadata?
- std.table.class.inc will need setFieldArray() to accept a second argument for an array of metadata key/value pairs whose indexes line up with the $file_list
- include.xml.*.inc will need to accept an array of key/value pairs for a file's row entry and insert them using setAttribute($key, $value)
- std.filepicker.list1.xsl will need to run the scaling code using the image dimensions stored as attributes in the "/root/file" tags and the bounding boxes specified in "/root/params/image*"
Is there a better way to do any part of that? I am trying to decide whether it is worth doing.
