Hello i am very interested in this tool i love editing my photographs but i want to make sure i install this add-on proper i DL'ed the zip file after opening it they are APPS so do i install them like i would any program or do i simply drag + drop them directly into my gimp plug-in folder?

Thank you for any help.

Hello molly.
Compiling GIMP Beautify Plug-in on GNU/Linux:

Make sure you have at least 2 GB of free space on /home.
Install "git" in your distribution. Also install the development libraries for the GIMP (libgimp2.0-dev on Ubuntu).
Open the terminal and download the sources from GitHub:

When the download is complete enter to the directory:

Run make:

On my computer (and Kubuntu 64bits) this has overloaded my CPU and that it took a while.
Install on your /home/USER/.gimp-2.8/plug-ins/:

You must have these binary files in your /home/USER/.gimp-2.8/plug-ins/:
beautify
skin-whitening
rip-border
texture-border

and verify that each one is executable.
You can find the plugin in "Tools" > "Beautify".

Thanks Rod for notice about this plug-in

Yes drag them directly to your plug-ins folder.
I am currently compiling Texture-Border (not sure how big that one is yet)
But the h file itself is 1 half gigabyte (534 MB)

Once again, thanks a lot YAFU.

Thanks for bringing it up Rod. What's the name of that font? The two Iron Maiden like fonts I have don't look too great.
