IH stopped finding images.

I switched host and for some reason IH doesn't add the additional pics for NEW item. The old Items are fine. but new items are not adding the extra pics

I uploaded all files with set perm. 777.

example of files

Main image ABC.jpg
extra images :
ABC_01.jpg
ABC_02.jpg

i can however add images manually but it's getting annoying.

Please Help
