Note also discussion
here & following. That is: currently there may be pixhost.to links shown in page/thread view that instead revert to original pixhost.to links in post view, which means IHG cannot resolve & will fail to download.
Temp. solution: if the images are posted in galleries then simply access one image (from page/thread view) & switch to gallery view & can use IHG there. If the uploader
didn't post them in galleries then manual is the only way to download, for now.
