How do i check the an image before uploading

[syam]

Hai frnds.....

Please Help me. I want to validate an image befor uploading, to check whether it is a valid image or not

[treecool]

there is many way..
the way that i usually used is comparing the extension of the file.
with " substr " command --> see PHP manual for the rest.

One thing I did with my uploader script was to upload the image to a defined hidden located on the server and submit the information on the file to a query table in my database.
Then when I log in, the images will appear on my screen in order of their upload and I can verify them that way.

So,

File is uploaded
File is placed in "uploads/queue/" folder.
File Information is placed in my "queue" table.

When I verify the image
File is moved from "uploads/queue" to "uploads"
File information in database is moved from "queue" table to "files" table.

Hope that helps give you an idea where to start.

What do you mean by valid? Just that it is an image? Or do you want to accept only certain types of images, e.g. only .gif, .jpg, .png, .bmp, etc.? Or do you want to limit the file size? Or do you want to limit the image dimensions?
