I apologize for misreading your post; you were referring to photos and not texts. But the answer is similar; unless you had them backed up somewhere, they are likely lost. If they are on your SD card, you may be able to use retrieval/recovery software; I haven't used one in a while, so you'd have to Google it.
And posting personal information is against the forum's Terms of Service, so I've sent your post to Moderation so that the personal info. can be removed.
