help pls... anyone

I don't know the name for that style or the plug-in needed. But the thing is you have one big photo and may be thousands of small photos. The software rebuilds the photo using the appropriate small photos. you see the original image is actually made of tiny pictures when you zoom. what is the name for that effect? can we do it with photoshop? do i need a plug-in (and what's the name of it)? or can anyone suggest any other software? thanx...

I typed "photo mosaic" into google and got a few hits, not sure about a specific name. As for software, no suggestions here.

To answer "can we do it in photoshop", yes you can. Im sure there's plenty of filters that will do it for you, though with a little patience you can do it by hand. Basically select your base photo and a group of photos you'd like to tile over it (resized fairly small). All you need to do now is start matching colors...like dark photos for hair, blue photos for sky etc. Just tile them and a couple of hours later you shoud have a result.
