I create overviews for mi tif images using gdal: 

gdaladdo -r cubic imageName.tif 2 4 8 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 64 128 256 512 1024

It improves loading speed a lot.

What format are your imagery files?
MapInfo doesn't seem to favour jpg files but better with tif files.
Are your files on a read-only server?
As MapInfo will try and create some extra index files and if it can't
create them - it grinds to a crawl.
Alternatively convert or merge them into MRR files - unlimited file
sizes and fantastic performance.

We have been using MapInfo for 15 + years, and have recently moved to v 2023
Opening our seamless layers of Ortho Photos has become un usable.
files are taking 15 minutes to open.
Is there something in MapInfo that would be causing this? or could it be
hardware/network related?
