XF 1.5 Problem importing VBulletin 3.8 photopost into Xen Media Gallery

[AnimeAi]

I've been running a test import on my site and have completed the VBulletin import. The photopost media import has hit about 50% and stalled - no more admin logs generated and no php error logs. It just sits there refreshing the page. I can't see any way to find out what it has stalled on...

NOTE: I'm importing to XF 1.5 so I can also import Downloads II to the resource manager. Everything will then be upgraded to 2.0.

Help/suggestions are much appreciated!

Finally found the problem image and deleted it from the main photopost install - it was a pain to track down as I had to search by date (not an easy task in photopost with ~200 categories!). Thankfully it was just a single broken image, the rest imported fine.

I'm now having issues with the firefox tab crashing while importing comments which appears to be taking ten times longer than the image imports!
