You could achieve this by creating a custom renderer which would draw thumbnails. The images would be rendered directly to the map. Another option is to implement a custom map canvas item that will show thumbnails on top of the map. Each approach is better suited for a different scenario. If you want to print such map, implement a renderer - map canvas items are not a part of the print output. If you want just browse the images, map canvas items are probably a better solution - for example, they could be loaded and scaled in a worker thread, thus achieving a better user experience. You can check out the player plugin [1] from my former qgis-mapper project - it uses canvas items to show thumbnails of geotagged images along the track. It also supports grouping of images when there are more of them close to each other.
