After migrating to G2 pictures do not show up, (even the new pics I uploaded)

hi!
I have been reading the facs and nothing helped me.

you can go to www.karinasensio.com/gallery and see that the pictures do not appear.

Thanks for your help

Hi,
It seems that my problem is related to the available memory that PHP has access to, because I can upload a very small picture.
I have no access to php.ini. I tried to create one, but it does not work.
So I went into htaccess file and tried to paste

php_value memory_limit [80000000]

but it doesn t work either. Where in the htaccess file should I paste it?
thanks for your help

here is the script of my htaccess
