This is a followup to #78537.

Consider the attached script. It creates an image and a texture node. Image.source = SINGLE IMAGE but behind the scenes Image.image_user.frame_duration = 100, which apparently causes memory problems according to the other bug report. You can see that by switching the source to MOVIE.

It is easy to avoid this problem by adding the line

node.image_user.frame_duration = 1

whenever a texture node is created. But then you need to know that you should do that.

I do not consider this to be a bug. The frame duration should only be used for frame sequences, it should not be expected to be 1 for still images. Changing an image datablock back and forth between different types should not lose duration data.

Can I request if someone can make a script which will fix all materials in a blender file? To convert any material with
Image.image_user.frame_duration = 100 into a single frame.

I think the above solution is to either change to movie, or run that py files on every material
