ImgView uses a modular approach so it can support future image formats. A good example is WebP which I was able to bring to the Atari ST as a plugin. Many of my plugins are for obscure formats you may never encounter. Some are quite rare. ;o)

Issue tracker & Atari Forum
I have several unreleased plugins. I will not release anymore plugins only to have my work stolen. If you are wondering why updates stopped... well now you know. You can thank Thorsten Otto the thief.

The only solution is Otto needs to wipe them from his repo and directly call my plugins. If mikro has a conscience he will never merge those plugins into the official repo.

ImgView is now a private pet project just for me until further notice. Below is an older buggy version... again you can thank Otto for that.

• Relies on exclusive features of NVDI v5.03 (lesser versions are buggy!)
  NVDI official update or Installer with serial number or Preinstalled copy
• Plugin Pack, else it won't load anything

• AV-Server for drag & drop, like Thing Desktop
• NAES v2 for best results (worth every penny)
  Need an AES with real toolbars (otherwise extra features are disabled)
• MiNT v1.16.x or better
• Lots of ram, the more the better
• The higher the resolution the better, recommend a graphics card, BlowUP030, ScreenBlaster, etc.

fVDI is an unfinished project. ImgView won't work with fVDI alone. fVDI + NVDI is required. I've been told it works on the Firebee.
Milan VDI aka MVDI alone won't work. Installation of NVDI on the Milan is the same as fVDI, you must disable all NVDI*.SYS drivers. I've been told it works.
Any system that relies on an external 3rd party video driver will more than likely require NVDI loaded over top of it. NOVA driver would be another example.
The bottom line. There's no replacement VDI out there at the time of this writing that's a 1:1 match for NVDI. For all practical purposes ImgView requires NVDI 5.03 regardless of your setup.

ThingIMG doesn't work with Thing Desktop versions above 1.30 combined with a certain French AES. This was done intentionally to stifle user choice. An extremely lame decision. I don't use or recommend either of these packages.

ImgView might be the 1st application written leveraging the power of NVDI 5 for dithering, scaling, and transforming images on the fly. :oD
Please correct me if I'm wrong.

Contact me if you have a problem with a plugin or and idea for a new one. I need a copy of the image causing the issue.
