A Blender addon that shows thumbnails for image texture nodes in the node editor.

Note: If you want rendered previews for all nodes, not only image nodes, check out my new addon Node Preview instead. 

Required OS: Windows 10 or Ubuntu 18.04/19.10/20.04
Required Blender version: 2.80, 2.81, 2.82, 2.83, 2.90, 2.91, 2.92 or 2.93.

Mac OS is not supported!

Features

• High performance: Thumbnails are generated by a C++ worker thread in the background, the Blender UI stays fully responsive at all times
• Low memory usage: Each thumbnail takes up 265 KiB of graphics RAM (regardless of the size of the previewed texture). 100 thumbnails would use 25.6 MiB - a negligible amount.
• Supported image formats: jpg, png, hdr, exr, psd, tga, bmp, gif
• Cycles/Eevee nodes supported (Image Texture and Environment Texture)
• Octane nodes supported (Image Tex, Alpha Image Tex, Float Image Tex, Image Tile Tex, Instance Color Tex)
• No changes are made to the .blend, others without the addon can still open your scenes without problems
• High-resolution displays supported (works with Blender's resolution scale feature)

Caveats

• Thumbnails are not displayed for packed images
• Thumbnails of image sequences are not updated when changing frames
• TIF images currently not supported
