I guess you downgraded from 3.3 to 3.2.1 in the past? Unfortunatelly the Joomla Installed does not prevent this.

Not sure how many additional error you'll get with the database update but you need to remove those columns. In this case the column image_thumbthresholdsize in the table #_eventgallery_watermark.

Everybody who downgrades is having this problem. It's an unsupported use case and the Joomla installer does not prevent this.

The following snippet reverts the database changes from 3.2.1 to 3.3.0. Please install 3.2.1, run the queries and install 3.3. Please always install the package you downloaded instead of unzipping it.

Don't forget to substitute '#_' with your table prefix 'elev_' and remove the space character in 'A LTER' and 'D ROP'.

A LTER TABLE  `#__eventgallery_watermark` DROP COLUMN  `image_thumbthresholdsize`;
A LTER TABLE  `#__eventgallery_watermark` DROP COLUMN  `default`;
A LTER TABLE  `#__eventgallery_file` DROP COLUMN  `url`;
A LTER TABLE  `#__eventgallery_staticDROP COLUMNress` DROP COLUMN  `state`;
A LTER TABLE  `#__eventgallery_userDROP COLUMNress` DROP COLUMN  `state`;
A LTER TABLE  `#__eventgallery_folder` DROP COLUMN  `foldertypeid`;
A LTER TABLE  `#__eventgallery_folder` DROP COLUMN `metadata`;

A LTER TABLE `#__eventgallery_imagetype` DROP COLUMN `weight`;
A LTER TABLE `#__eventgallery_imagetype` DROP COLUMN `depth`;
A LTER TABLE `#__eventgallery_imagetype` DROP COLUMN `height`;
A LTER TABLE `#__eventgallery_imagetype` DROP COLUMN `width`;

D ROP TABLE `#__eventgallery_foldertype`;
