There are two critical factors to suggesting a solution - target format and actual data sequence. For electronic format, I'd animate it via movie or controls. You could create something where you pick which image is visible (or even two side-by-side). There are many ways to implement that. But if the target format is paper based (or even static electronic like a simple pdf) then it's more a layout question. And you have to consider how your audience will use or consume this information (comparing a month year to year, comparing the months over the course of a year, just as individual references, etc).
If format is a book/paper, I might suggest one year per two page spread (or six images per page). That's still 14 pages of maps, and flipping back and forth to do any comparison would be difficult. From the amount of data you have, you could also make each two page spread a single month - all of your January images on two pages, February on the next two pages, etc.
If a poster, I'd try to keep years/months aligned. So for your data each of 10 rows on the poster would be a year, and each of 12 columns would be the same month. In the case of your data, you'd have 37 holes in the grid for the months you have no image, which is about 30% of your poster being whitespace. With that many missing months, it may not be as useful to be able to easily compare from year to year.
