how to check image exist in javascript
I've been on the hunt for a simple little function that will detect whether or not an image file exists when a user selects the file from their hard drive or types in the location. Just need it to alert that there is no such file if it truly does not exist. IE only.

Is this for file uploading or something else?
I'm confused as to what you want to check.

Sorry! I didn't want you to think I was ignoring you... I just don't know the answer to your question.
The only javascript code I know for uploading and checking a file checks the extension of the file and makes sure it uploads alright, but I don't know how to check to make sure it exists before it's uploaded.
Hopefully someone smarter than me (which includes a lot of people) will be able to help you.
*Edit to add: It looks like you may not be calling up the function for your alerts. Have you tried using...
tester.onload=isGGood();tester.onerror=isBBad();
I also don't see the function for new Image(). Is it somewhere else?
gotta finish redesigning my sites so I can show them again.
