Presta 1.6.0.9 won't add more than one product picture

[amajazz]

I tried the 1-click-upgrade, but the latest version of PrestaShop had some huge bugs in it, so after someone told me that 1.6.0.9 is the latest good version, I upgraded to that manually. But now when adding a product it just says that it's not possible to add more than 1 image. Since I sell clothing, this is a huge issue. Please help! :'(

Had to work around this issue adding new items http://susitaika.com/fi/vaatteet/[spam-filter]tuubihuivi-ruusu.html
