Centos web panel problems with magento

Good, it's my first time with centos web panel and I am having many problems q've never had with other control panels.

1 could not do installation of magento, problem. Rename .htaccess by htaccess.text

I do not understand because linux is not windows.

2 I can do the install but now the images are not,
