I did these with GIMP, which is free and open source. It did not find an option to export IMG files, I did one in PNG and the other in SUN Raster Image, don't know if this works.

But at least reducing to 1 bit and dithering is doable with GIMP quite easily.

Thanks. Thing seems to only use IMG format.

Last week there was a Humble Bundle of art programs and Paint Shop Pro was one of them, now owned by Corel. I was shocked it's still about I remember using it on a 486 SX25 because the viewer was awesome :D

There's a sort of free version of Adobe Photoshop that Adobe abandoned because the online servers that they used to verify your serial were shut down, they released a official free key I presume for people who actually had it and were using it, in case it needed reverifying I guess.

Some info here :

Annoyingly I have all the keys for that stuff but lost Audition 3 when I wiped my PC to do a fresh offline windows 10 install on a new hard disk (online accounts list every program on you pc. My account finally deleted today) So now I have the key for Audition 3 and no Audition 3 :blonde: Photoshop doesn't have the format I need. Paint Shop Pro is going for £8 on ebay, so I might get it.

Does gif format work on Thing then? IMG doesn't using floyd steinberg dithering. No, just tried it. Just bought Paint Shop Pro 9 for £7.99.

PI3 is the format which Snapit saves as, and I can view these in XnView. Tried this format on Thing and after much back and forthing I believe Thing uses only IMG format for it's desktop pic. I have bought a download copy of Paint Shop Pro 9, which allows me to save as GemPaint which is IMG and I have just managed to use with Thing (Hooray!) Annoyingly XnView will view IMG and PI3 files, while Paint Shop Pro 9 will open IMG files but not PI3 files from Snapit, so I need to use both of these programs. Another odd thing is that you can't double click an IMG file to open with Paint Shop Pro 9 even if it's been assigned to always open with the application. The application has to be started first. (Just realised that I can drag and drop files into it's workspace though :D ) Still...this is all running on Windows 10. I think being able to get screenshots from the Atari and have Atari desktop pics has been worth it

Here's how to make desktop images for Thing on your PC using Paint Shop Pro 9
