In my case past, I created image using Photoshop w/Nvidia plugin on Windows, it worked by rewriting icontex.qrc with hex editor.
It was a long time ago so I dont remember... but I created it without any special knowledge.
I just followed the great tutorial left by pinky.

Also my main machine is a mac, so after understood the method of porting dds into Icontex, I remember creating png on mac and converting them to dds using a application called aorta.
Either method worked. and after that I think I basically worked on mac because converting with aorta was very easy.
It was a long time ago so my memory is hazy, but if dds settings are correct, it should be possible incorporate them into icontex.qrc any software.
opening my dds in the viewer, its displayed inverted. as far as I know, this is the default and I remember that both official dds and custom dds were inverted in same.
I don know the reason behind it, but I also created images without giving it much thought.
I post some examples of my work. I don't see many custom icons that are similar to official icons, so I hope this will be helpful.

8n and 8nf.dds are alternative icons for the "user column" that myself.
Ive recreated the familiar smily and friend column icon used in XMB versions prior to 1.0, and adding effects from later FW.
7n is the retro category icon from multiMAN ported to the XMB.
I still use the network column as the emulator column, so this invader has been facing me on the screen for a long time.
n_.dds is the PSPs extra column icon ported to the PS3 XMB.
I used to include it, but now moved the extra column to PSN column, so Ive removed it. but It worked fine.
Ill post an example w/effects removed, in case its helpful for someone, custom folder 44n_2.
The parts where the effect is hollow are displayed as no effect, but this isnt used anymore as it didnt produce very visually interesting effect.
At the time I also created a version which holes were filled, but it didnt make much difference.
Because these base are grayscale, the drawn patterns dont seem to stand out as much as patterns made by carving them out.
