I have one basic question. I have project where I need more sizes of one picture.

Yes… During uploading you make thumbnails… and so on… I know this story … performance vs. storing possibilities.
So I save original img, a make 2 thumbnails copies for example max width 100px and maxwidht 200px with respect to ratio.
Now I need show image in 150px max width so I take saved img(200px) and …..

I use getimagesize() for calculating showing width and height respected to ratio,
or I set max-widht and max-height and I leave it for browser (browser make it for me),
or I set width a keep height: auto (but I want also limit max height)

So actualy I use php and getimagesize() but this function every time work with file and I am little scared. When you process 1 img it is OK but what about 20 or 100.

And… another idea, while uploading I save to DB also size information, for this I have to save data for 3 img (now only original one) this complicate everything.

So … any ideas? What is your practice? THX.

    Two images, at a maximum: A thumbnail, and the original image are sufficient. Make sure that your upload page is well-secured, because I’ve seen a website taken down through DoS (abusing an unprotected image-resizing page). Also limit the maximum upload size, to prevent abuse.

    You can use the max-width and max-height CSS properties to limit the size of your images.
