Image links from not-so-related websites to increase indexability?

We are about to publish a website with around 200k web pages (content is quite unique, some sort of archive) and I'm trying to explore the oppportunities for higher indexability.

So what I thought is, providing some image links to this new website from the other websites my company is controlling. This way I'm hoping to get more PR-based indexability without raising any flags with text links.

What is the experience of the folks here about that? Do you think not-so-related image links (well like an image link from site A's blue widgets page to the new site's "blue widgets" tag page) would also raise penalty flags?

Each situation has unique qualities, but my guess is that Google already knows that your company controls these various domains and that no PR will transfer. Also, unless you go crazy, no penalties either.

If these links would make sense for the visitors to each of those other domains, then add them. But don't expect much indexing boost unless you also begin to attract more freely given editorial links (and preferably deep links) from third parties.

Well, regarding the "would make sense for visitors" part, I'm not going to hide that we would be kind of pushing it - but as I said we'll try to link pages with similar themes anyway.

The problem is, the niche is one, where people usually do not visit websites about that topic every day, but where they depend on some search engine help to get there - maybe once a month or 5 times a year. We have already been acquiring deep back links to our pages which are already appearing in search results. I am just trying to explore ways to increase the number of pages we have indexed, as I am kind of confident that we will quality back links in a fast manner even if we make our pages make it to the top 10 search results. I understand that it is a chicken-egg issue but that is what we face.

Thank you for the insight.
