This may be a bug for image and not image assist.
Images don't display, even after truncating all cache tables. Nor do they display in image assist popup window. New images work
Debugged to the image table
I'm not saying this needs to be 'fixed' but my solution was as follows:
Using a query as follows i copied content from my files & upload table to populate the image table
INSERT INTO hmage (nid, fid, image_size) SELECT u.nid, f.fid, f.filename FROM files f LEFT JOIN upload u ON u.fid = f.fid WHERE filename = '_original' OR filename = 'thumbnail' OR filename='logos' OR filename = 'preview'
I have 4 presets of images, original, thumbnail, logos and preview so replace as need be.
