(why the issue was filed, steps to reproduce the problem, etc.)
Setup - I used a patched development version of Media and Media Gallery - see steps here: http://drupal.org/node/1244204#comment-6678836
Recreating the problem
when using the drag-drop re-ordering is that the images increase in size after reordering, do it again and they get bigger again, do it again and they get bigger, etc. Again, I'll raise another issue if it hasn't been raised already.
(description of the proposed solution, the rationale behind it, and workarounds for people who cannot use the patch)
Looks like some variable is not being reset when the gallery is refreshed - I am guessing that the image size x and y dimensions are being added to the same existing x and y dimensions thus resulting in a bigger thumbnail.
(reviews needed, tests to be written or run, documentation to be written, etc.)
Recreate problem using steps above. When fix found, do steps to see if fix works.
User interface changes
(new or changed features/functionality in the user interface, modules added or removed, changes to URL paths, changes to user interface text)
User interface should not need to be changed.
(API changes/additions that would affect module, install profile, and theme developers, including examples of before/after code if appropriate)
API should not need to be changed unless work is still being done in Media 2.x-dev and Media Gallery 1.x-dev
