Images With No Extension

[webmasternovis]

Hi all,

I've created a file upload script with PHP and at the moment images don't have an extension once they are uploaded and into the site. Will this be ok? They seem to load fine at the moment...

Thanks,
Mike

They load fine for you because your browser is smart enough to look at the structure of the file and determine that it's a gif, jpg, png, bmp, svg, eps, etc. Not all browsers are as smart as yours and there will be some complaints about broken images. Unfortunately, I don't know what percentage of browsers will have problems - I suspect it's pretty low - but you should test that theory on your own to be sure.

Extensions are also useful for reference purposes and server maintenance. Unless there is a reason not to keep them keep them.

Though I do understand if you are auto generating the name using an id it can be a pain as you have to do a lookup for possible different possible file names via an extension list.

Though the server maintence/ future use of these files outweighs the ease of no extensions. What if you want to know how many are gifs? How many are jpg's? A lot of opereation systems rely on extensions to know what application to open if you ever download them. Building a function that scans will allow you to do things like upload flvs and automatically open them in a movie player instead. Scan in order of probability( ie jpg's then gif's etc. ) and increase of server load will be minimalised.
