Why get decoded images saved into Translation Database?

  • I’ve found another incompatibility with the translation plugin TranslatePress. Translatepress stores all terms from translate()-request via the gettext hook in the Database. As a result I currently have more than 6000 entries of “data:image/pnga;base64…” values in my translations database. Since there is no Text domain specified, it is not easy to filter them.

    I use the Captcha Image method and all the images are stored in my translation database table like this:

    data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAH0AAA…

    the full decoded image is saved, I only post the beginning here.

    I searched the code but I was not able to identify the place where this happens. Before I dig deeper into it I’d like to ask you if you have a clue where the captcha plugin does something with this string that could make TranslatePress via hook etc. believe that this is a translatable string?

    Hi,

    I just deleted another bunch of 114000 of those decoded captcha images from my database after getting information from my backup plugin that my backup storage is running out of space…

    So I just wanted to ask if you have any idea on where those image strings find their way into the database?

    Thanks.
