Welcome to the Q&A Forum

Devon, Having multiple images linking to a site is not a problem at all, actually this is a very common way to build links to a site. As always it helps if all the tags are included in the image when it is posted (ie title, alt img). To make sure these are included it is often easier to send these sites the code to add to their blog, or have the code available for copy and paste. It's fine that the image is hosted in one place, the 'juice' will be passed from the site that has the image link. Hope this helps. Nick

Long story short, if you can host your sub-domain in a sub-folder, it'll be better. However, a lot of times for security issues and hosting constraints, companies end up hosting blogs on separate domains or sub-domains. I'd suggest you look into reverse proxy. That can make your blog URL look like yourdomain.com/blog I hope that helps

Devon, If relevance between two subdomains is low, the value of links pointing from one of them to another will be low, as well--even though they share the same root domain. If they're as different as you say, it's probably best to tough it out on a new domain. Nonetheless, it shouldn't be inconceivable that you could come up with some overlapping concept between something on the two sites about which you could write. Such an article/page of content/blurb added to the old domain and linking to the new domain could give the new site a little boost in visibility/traffic/awareness.
