Hi @And27, sorry to hear that.
I have translated your question to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.
Is it in the Album application the photos are no longer available? Do you know where the photos were stored, the internal storage or on a SD card?
If you have a computer you can connect your device to that one and see if you can access the photos this way or if they are on the SD card, try inserting it in a different device.
I hope that helps!
