Hi @Magugis, let me see if Im can help out here.

Once the photos have been deleted from the album app, they are deleted from the internal memory as well, I am afraid. The only way to recover the photos is if they have been backed up somehow. If you have your user data backed up to Xperia Companion you can restore them using the restore function in the same program. Form more information on backups and how to restore them, click here.
Another good thing to check is whether the photos have been backed up automatically to your Google account. In order to check this, you can either use the Photos-app on your phone or through a browser using the link below.

I hope that helped!
