"Fluent Blue" version
Hello,
First, thank you very much for providing this great complementary functionality app.
Would it be possible to create in addition to the yellow default folder, a "Blue" one ? I could recommend you asking @Mr4Mike4, who made a very nice "Fluent Blue" color for 7-Zip files, to provide the template for you.

Original request from ElevenForum
If I have the original author's explicit permission, probably doable.
Thank you for your fast answer @hahagu !
Exactly, I wrote to @MrMike first (in PM on DeviantArt) about this request and he will send you his template if he agrees. Thanx for accepting the request on your side, that's nice.
Meanwhile, on the Windows 11 Custom Icon thread of ElevenForum, a member just made a different gradient blue template plus the shorter one, made especially for your app on my request. On my side, I reworked the icons in smaller sizes, exactly like the original ones. I also reworked the gradient top border. You maybe won't need these full icon resolutions as I noticed you are just using the 256 PNG templates, but if ever in the future, you intend to include conversions in these extra sizes, the full templates are ready. Otherwise, just extract the 256 ones in PNGs.
They have a clearer appearance when small sizes are displayed, but I must admit I found it disappointing when I discovered Windows does not include the last 3 smallest sizes (front cover is no longer small) - but it's not the case with your app. So I made a try with the yellow shorter cover, but not with the gradient blue yet. If ever you need it, just tell me. Meanwhile, the 1st replica is just good for replacing the imageres.dll one.
I also learned today that Windows 11 has now a new front folder for displaying thumbnails, since Build 22557. Maybe you could also include it as another template, cause your app is still useful as customizing as you can choose the number of pics, and makes the folder permanent and portable. 👍
JPG : New Windows 11 thumbnail folder. (on the right) You can spot Windows still don't apply thumbnails in the 3 smallest sizes (full cover).
Thanks for reading, and for your great work.
Cheers
@Mr4Mike4 has just done the job ! He should post the link here anytime now.
I suggested we could add the new front thumbnail cover from the 22557 build I mentioned just before. I don't have it at the moment, but will send you the original yellow and the fluent blue asap, if you want it.
See you

Thank you Mike @Multisquid2k3 Didn't know you had 2nd account.
@hahagu, tell me if you are interested in the latest build 22557 front/cover folder.
Here's Mike's DeviantArt page, in case anyone needs.
Alright Thanks! I'll look into it as soon as I have some time to do so 😅 I have been busy with some other stuff.. so..
Thank you @hahagu !
and there is really no rush, of course. It is nice from you to accept envisaging to add extra templates.
I'm still waiting for @lexx911 answer (creator of new thumbnail folder templates). I was mistaken about these, thought they came from 22557/8 build. I'm trying to tweak them a bit, to get rid out of blur here and there (probably due to conversion from 512 to 256) so I will also suggest a new cleaner version, in the near future.
We stay posted !
Cheers
