Hi! sorry, my complete themeforest username is superfulanito I didn´t read your instructions till I had created my account here :S.
I have some problem showing images in my blog! not only thumbnails but the images inside my post too! I tried to enable writing in my wordpress folders yesterday but they hacked my site, so I restore everything and I didn´t enable writing this time. The homepage banner images were uploaded after installing your theme but they are not resizing correctly either.
