hi,
after some testing,
The image functionality is usable and I have successfully build
working catalog component with images and thumbs (ebay style) ,
minor bugs and ideas that I've found:
///////database
//
checkbox if format is allowed or not doesn't change
the behavior or the uploader
///////////// on colection
//
thumb size definded x and y
nothing selected from: center, crop, fit
image has other proportions
//
center only or crop only - same result, crop?
//
one dimension filled - no change
one dimension + crop - co change
//meta:
//
when filled "Image title"
strange link text in on hoover box appear
//
modal preview: not sizing
///////////// on fly
//
modal preview: not working
//
1:n images work!!
have no option to set thumb size, crop, center, fit
and

modal gallery preview
//
two toolbars on top and and on the bottom
duplicates the buttons everywhere
//////////////// on form
// when editing the existing image the default icon
is "Delete all images nad thums" the behavior is ok "Do not apply and changes"
//
no 1:n image uploader would be superb
hope that helps.
PS Have you found something in >>> file.php on line 2058, should I reset some configuration on my server ?
