[1.6.0.8 -> 1.6.0.9] Problem with uploading product images

[Logical IT]

Today, I upgraded a clients site from 1.6.0.8 -> 1.6.0.9 and after the upgrade I discovered this error when trying to upload a product image - 'an error occurred while creating an additional image'

This what I did to debug and fix the issue:

1. I Turned on PrestaShop developer mode
   - To put PrestaShop in development mode open /config/defines.inc.php file
   - Find the line of code that reads "define('_PS_MODE_DEV_', false);"
   - and change it to read "define('_PS_MODE_DEV_', true);"

3. in Chrome browser I opened the javascript console (f12) and discovered the following error:
<div class="alert alert-danger">
            <button type="button" class="close" data-dismiss="alert">×</button>
                            Unknown column 'hover' in 'field list'<br /><br /><pre>INSERT INTO `ps_image` (`id_product`, `position`, `cover`, `hover`) VALUES ('15', '3', '1', '0')</pre>
</div>

4. It appears the field 'hover' is missing from the ps_image table in the database. To fix this I simply created a new field called 'hover' to both ps_image and ps_image_shop tables. I copied the same field definitions from the 'cover' field.

Did this resolve the issue completely?  Also, your post looks like its missing a #2.  Was there another step?

Yes, it fixed the issue, however since working with the latest prestashop versions, I have not seen this bug, so I guess it's been fixed in the latest releases. Sorry, looks like I can't count, step 2 is not missing.
