404 help

[cde]

New webmaster here, planning on starting a Image Hosting site, before I start trying anything with porn first. Thing is I need some help with 404's, and since the majority of people on here are seasoned webmasters, I thought I should ask.

Is it possible to have more then 1 404 page due to different directories? Or to have a different 404 page depending on refer/no refer or how it was requested? Since I'm running an image host like tinypic, I will be removing images after a while or depending on the content (Like illegal or liable to get my site killed) I know a 404 will be important. Mainly the images will be uploaded to various 3 letter subdirectories on the main site.

So for example if someone loads the image directly it should show a html/php 404 while if it was loaded via a img tag on another site it will show a image 404 on the site that it is linked on. Finally, the rest of my site outside of the image directories would have a separate 404.

Well, if it was simple hotlinking to a set number of images, I could just replace the image to prevent it, but since the number of images will change daily its a bit more complicated then that.

Any help would be appreciated. TIA.

what im understanding is you wish to have different 404s based on directories. you can do all of this via the htaccess files with specific instructions
