How do I get an image as output through get params?

Question

I've been making a members registration system with profiles and want to get their avatars from a single file (like "/img/avatars?id=10005860538397&size=250x250"), is it possible to get different images? I've thinked of using PHP function to pickup an image from the folder like (/img/users/avatars/1000586053897.png) but it'll output the HTML markup. Is there any way to get the (image)?

Answer 1

The simplest way of achieving this is to use the .htaccess apache configuration file and generate a virtual URL for the file.
The URL should be like /avatars/100005860538397
The would fetch the 100005860538397.jpg file and attach it to the passed virtual URL using the mod_rewrite Apache module.

Answer 2

I've thinked that first getting the image and encoding it into base64 then outputing it onto the avatars.php. Will it work? As the code is in another file instead of in src attribute?
