Is the file extension correct? folderblog in the stupid standard version 3 is only able to load .jpg, everything else like .JPG or even .JPEG will simply not be loaded.

Yes, is correct. The problems appeared after I deleted some pics viva ftp. I had that before and dit delete all fb files on the server, made fb completely new and transfered it to the sever but that didn´t solve the problem.

On a linux server it is a huge difference between .jpg and .JPG or even .jPg. Whoever invented this fact, I will come and kill that person. ;)

Hmm... if via /post the pictures "physically" exist on your server in the right directory, they also should be loaded. Please check whether all files have the correct rights, so also fb.php. Try one thing, go into the photos directory where the newly uploaded files are (which dont show up) and give 777 to all of them, plus the folder. I´ll explain later why, but maybe this helps.

o.k. I did it and it dind´t change anything.

First of all, it would have made sense to say that you are using the ikue reloaded version and not the standard 3 beta. Next thing, it seems you switched use_alt_urls on, right? Switch it off and see what happens, in general I can see the pictures on your website and without a more detailed problem description it is difficult to help you.

No, use_alt_urls is set on "0". The pictures you can see were posted via ftp the not visible via http. The problems appeared after posting some pics via http and then deleting some of them via ftp. Even if I delet the whole fb on the server and upload it complete new the pics posted via http are not displayed.

This is not logical, I guess you made a mistake with giving rights. I never heard of any case where deleting by ftp makes problems. What you could try to do is check whether there are any traces left of the deleted images, look into the comments directory and also whether there are corresponding .txt files where you stored the photos. Delete them and see what happens.

Changing from .JPG to .jpg worked for me! Thanks!
