1. No one has ever reported view issues and thats strange I dont know what would change the stats like that so I would have to check that out. Try turning off the category cache in admin global options does that help?
2. well I dont use that application so I cant really respond but do suggest you check out the photopost pro 7 beta that has the new SEO
3. My suggestion to any image you may have in the header etc you make sure whereever that link is that its a full url to that image so that it can be shown. I use all the latest browsers so they dont show broken image links.
