Hi,

updateimagesystem.php fails if you apply the sql update before.

In the upgrade doc, you should apply the sql update before running the scripts. But the last two lines of the sql update are:
DROP TABLE ezimage;
DROP TABLE ezimagevariation;

updateimagesystem.php fails because it needs these tables.

So please change the doc and move the drop table commands to the end of the update script.

Best wishes,
Georg.
