My general product name is widgets.
These will be some of my categories:
Movie widgets - Celebrity widgets - Animal widgets, etc...
Within each category, such as the Animal Widgets category, I will feature products whos image filename could either be named:
My question is, what is the smarter way to name my product images? I'm planning on having over 1000 products, and I'm not sure if it's wise to have my main keyword in each name.
It's important to note that my site will have the term widgets all over it, within anchor text backlinks, title tags, etc. Would it be overdoing it to have my main keyword within the thumbnail and fullsize image filename?
