    Yeah well thats a "Slippy" map and have a look at Leaflet.js or some similar web API for doing that. The software side is doable, easy if your a web dev or programmer type. If you get a load of images together then id be glad to host them here along with our slippy maps.

    for the way google stitches satellite images together
    is almost 100% automated

    but basically the tools are available
    these are just the ones i use

    ISIS3 = for georeferencing images of NON!!! earth images and blending them into a planet or moon map
    ( mercury,mars,jupiter,...)

    for earth and odds and ends
    Qgis , GRASS , and GDAL

    now Qgis uses both of those anyway in the backend

    using a georeferenced and mapped image -- qgis can do this you can stitch them in qgis

    ------------------------------ added ----------
    id take photos from above using a jig for the camera.
    for that Nip2 dose a great job

    That’s great thank you guys. I had a quick google about slippy maps earlier. Will have a look into other software mentioned later on. Thanks again! Glad there’s some software out there to do this.

    One thing you will need to worry about is orthorectification. This is one of the things that has to be done in real life remote sensing. Orthorectification is an attempt to "flatten" out the image to compensate for the perspective effects from the releif. This requires a digital surface model, or failing that a digital elevation model. If you look at stitched air photos of cities from a few years ago, you can see the buildings skewing in different directions in different fragments of the mosaic with odd effects along the seams. This was because they used a DEM that included the ground level, but not the buildings. Newer mosaics often use DSMs that include the buildings and so appear as if you are looking straight down on every building at once.

    There are ways to use multiple overlapping photos from different locations to build a 3D model of the object being photographed. This is called Photogrametry and it is often used with remote sensing images, particularly air photos. OpenDroneMap is an example of photogrametry software intended for use with photos from UAVs. You should be able to use this for orthorectification to get a seamless mosaic.
