CUTENEWS
When I first started my graphics site journey, Cutenews was THE blogging script/CMS; since then it has been updated (pretty recently) and improved -- especially in the template customization, the security, the news and the categories sections; although a bit heavier than other scripts here, its more recent update makes it more compatible with newer servers.

FUSIONNEWS
This is the script I use to manage Hakanai and a few other sites; very similar to Cutenews but lighter, with a better security and moderation system, easier and more customizable news templates, a more approachable admin panel (especially compared to Cutenews' latest versions). Just like Cutenews, this script doesn't require a MySQL database. It's also the oldest script here, only compatibile with PHP 5.6, so it might not work everywhere.

ICON SORT
This is the script I use to showcase my icons and bases on Enigmaticons, but it also works for any kind of small-medium images that don't require links (icon textures, signatures, favicons, etc.); the script basically sorts out the images in alphabetical order, all you have to do is create the folders for each category you want. It's compatible with PHP 7, which makes it more up to date and compatible.

FANUPDATE
FanUpdate is another blogging script similar to FusionNews and Cutenews, but with more advanced features - the option to customize each news categories differently, very easy smilies customization, extremely strong security options are the ones I love most; FanUpdate requires a MySQL database to work, but setting it up is still as easy as Cutenews and FusionNews. It's compatible with PHP 7 (via update, so you should first update the old version and the replace that with the PHP 7 update), which makes it the safest script among these.
