MWL flooding database’s wp_options with transients

Hi, sorry for the new post but I added this new issue in a different one and it might be missed.
And it’s become quite serious.

Now I’ve noticed that our wp_options table has grown exponentially in size in just 24hs. And all the new entries are mwl transients.

During development I didn’t pay much attention. But see, the wp_options table is 4.8Mb in size with 2599 entries… 840 of which are for _transient_mwl_exif_ and another 840 are for _transient_timeout_mwl_exif

And I noticed that because once I delivered the site to my client, in only 24hs, the wp_options table has grown to 12.2Mb. And all of the growth is coming from your transients. Now, wp_options has 10121 entries, 4622 for _transient_mwl_exif_ and another 4622 for _transient_timeout_mwl_exif entries

So, in just 24hs the database got 7.4Mb, 7500 MWL transient entries…
Our site has about 2.000 articles, all of them with at least 2 images, times its resizes.
How is the database going to deal with this in a week?

Please, have a look and help with this. Thanks in advance
