I need some little .png icons for my Database Management tool's treeview

[RedOctober]

I have a main form TTreeView that has nodes for these different objects:  Server,  Database, Domains, Exceptions, Functions, Generators, Procedures, Roles, Tables, Triggers, Views.
I have the TTreeView connected to a TImageList and I have one image in it (a green checkmark to indicate "Connected"), all working correctly.

I would like to use a different icon (.png) for each of the different objects.  I would like the icons I use to be easily recognizable industry standard-ish icons. (Example: A database is a "barrel" looking thing)

Does anyone in the Lazarus, or Free Pascal forums know of an icon set I can use for this application?  I've been searching for days, and all I can find are icons for arrows, and everything else except for representing the objects I need.

Thanks in advance for any help you can provide.

If I understand correctly your request, you are more likely to find those as "free fonts" (Under CC-BY), e.g. The Entypo Pictogram Suite, Font Awesome, IcoMoon, Ligature Symbols, etc.

See these two icon sets which Lazarus uses -- Silk icons (http://www.famfamfam.com/lab/icons/silk/) and Fugue icons (http://p.yusukekamiyamane.com/)

These icon sets are under Creative Commons license, can be used in commercial applications, you are only required to mention the author and provide the link to icons' web page.

And yes, they represent databases as barrels.
