The "any format" aspect is probably going to cost you. I am not aware of any free component that does that.
 You might try looking at http://leadtools.com/ or http://skylinetools.com/imagelib/index.html neither of these solutions is inexpensive however they are fairly complete.

I've looked, but these seem to be a massive overkill for what I actually require.

I'm building an HTML editor. The main editor component (similar to a richedit), when it requires an image to be rendered, fires an event which includes as a parameter the name of the image. The implementation of the event then returns a graphic object which has loaded the image.

This is fine for locally stored images (TBitmap.loadfromfile) etc, but when the image is web based - as is frequently the case - I've no suitable TGraphic which can access the resource.

So, all I need is a delphi component, deribved from TGraphic which can do the above, preferably able to handle JPG,GIF,BMP,PNG etc.

Sorry, I have always had these big hammers available to me so I really am not aware of any components that do just those things.

There are all sorts of image display comps available on Torry's Delphi Pages http://www.torry.net/quicksearchd.php?String=Image&Title=Yes
However I did not see any that would do the download for you. You may have to tackle that step using INDY

I finally worked out a solution by trawling through the VCL source, after all it can't be an uncommon requirement and I eventually found the solution.

Use a TDownLoadURL action (extactns unit) to download the image to a file. This is exactly what I wanted.

Thanks for your help anyway.
