When using images it is a nice addition to your toolset to use a collage. Not only is a collage good for combining multiple pictures, it results in a end result that is usually more interesting than a single picture alone.

Anything that captures attention must be leveraged on your blog because your audience is literally "surfing" the web, and if there is not instant gratification as to what they might find on your website, they will go to the next.

Anyway there is a great programme for the PC that does a cool collage

In fact it is called COOLLAGE

Here is an example I have done. Admittedly I made it a 1 min movie with just the collage as subject and added a voiceover but the original collage on it's own is quite effective
