Starting with v5.0.0 build 3753 it is now possible to change the FlashFXP state icons.
This is an advanced low-level setting that must be done by editing the flashfxp.ini file directly within notepad
Open flashfxp.ini
now under the [main] section header insert the following line
CustomStateIcons=<path\to\custom\icon\state\folder >
The path can be relative for those of you using the portable edition such as .\icons to reference a sub-folder within the FlashFXP program folder. You can also use system environment variables in the path such as %HOMEDRIVE%\%HOMEPATH%
Within this folder create 6 files with the following file names.
205.ico = connected state.
305.ico = icon with active schedule.
405.ico = connecting state.
505.ico = transferring state.
605.ico = this icon is used when no other state is true.
705.ico = specifically for the system tray when FlashFXP minimized to the tray and locked.
If a specific icon file is not found (or fails to load) within the icon state folder then the stock icon is used.
The icons we use in FlashFXP consist of RGB/A, 256 color and 16 colors with the following sizes 48x48, 40x40, 32x32, 24x24, 16x16. The icons used within FlashFXP were created by Filipe Oliveria (X3) exclusively for FlashFXP.

When creating a new icon set use the stock v5 icon set as a reference.
If you create an alternative icon set, please let us know we'd love to see them.
