How to generate a collage image like show below. I would appreciate if you can let me know if there are any online tools or apps which do this. Thanks!

Image Magick is a free command line tool to process images and they have a feature called montage. Go take a look.
ImageMagick® is a software suite to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 200) including PNG, JPEG, JPEG-2000, GIF, TIFF, DPX, EXR, WebP, Postscript, PDF, and SVG. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.

Use ImageMagick montage like this to get your montage 10 images wide and with all images abutted together with no space between:
montage -geometry +0+0 -tile 10x *.jpg result.jpg
My images repeat because I didn't bother finding 1,000 unique faces :-)

Thanks for the above answer of using ImageMagick. I used the below command. Also make sure that ghostscript is installed (available via brew on OS X)
montage *.jpg -geometry 40x10+0+0 -tile 18x10 tiled_image.jpg

The more difficult way to make such image would be by basic photo editing- creating a big white background and copy- pasting the images you like over there but that would take too much time so just google something similar to "collage maker" and you would find lots of tools suitable for any beginner computer user. I would suggest downloading one instead of doing it in a browser if privacy matters in your case.
