Nanuky, we have tested uploading photo function on your site via the Mobile version on the mobile phone and haven't got any errors. Everything works fine.
Please, may you provide us the following information :

What browser do you use - name and version?
Did you try to use another browser ?
Can you upload a photo via the Mobile version on a computer ?

Hello,

thanks for a answer, Yes when i use the Mobile version  on PC i have no problems.

I have test it with my Samsung Galaxy S4 too, but there i can click the icon for Image-Uploading so long as i like and nothing happend or opened.
On my mobile i use Opera Browser, IE, NextBrowser and Chrome, i tested all.

Some users have no problems and some can do nothing.

Regards
