Problem: Special Search on Commons does not show all thumbs (example).
Proposed solution: Make it show all due thumbs after 1 user request, for example build in an automatic ctrl+F5 page refresh till all are loaded ... but better: clean up the code that prevents pages to load fully in one go. Make PDF-search optional by default. Investigate endless loops.
Who would benefit: Categorizers of large collections of images
More comments: Thumb display changes and loading issues were already discussed in 2022 here, but the issue of never loading of all of the thumbs in large searches (100-500 items) was never solved yet.
