Once you get to that image (I gave up before I got there the first time) you can go forward and back to see the other images. However, none are of any use.

The photos need to be sharp and we must be able to read what's on the devices.

sir i do not have high definition cam with me, that is why images are not clear, and i have uploaded these images only for indication, i can provide you all the component number's and other details if you require, i already mentioned the transistor number if you want me to mention other also i can mention it pls.

You don't need a high res camera, you simply need to spend some time getting better pictures... If the camera can't focus up close take a step back and let it focus... Add more light so it can focus easier, outside during full sun is an optimal time to take pictures... An out of focus photo is just about useless, a less zoomed in, in focus photo is far more beneficial... Especially if you can comment the part numbers that are not visible...

Try taking a step or two back, take an in focus photo even if it's not tightly focused to one area...
