    GD doesnt handle BMP files by default, I beleive there is a third party function available for doing this but cant remember the link, suggest a google search.

    Why are you trying to use an image file in a format that isn't supported on the web? Images for use on the web need to be GIF, JPG, or PNG format in order for web browsers to be able to display them at all. GD supports all three of those formats.

    I strongly go with you felgall but what if client don't understand man .all other three working fine with gd.Tell me one more thing the thumnail created via gd is that a valid image i mean what i did is i create a thumnail in .png format and i used the same image and sended it again for thumnail again it shows me error in image so i am bit surprised that thumnail created are valid or not.

    thanks for dropping your advise on my post
    regards

    It doesn't matter what the client wants to use for images - you have to convert them to GIF, JPG, or PNG in order to be able to use them on the web at all. That is a part of the job of converting the client supplied content for web use. If you upload BMPs then you will make the page extremely slow to display and the BMP wont show anyway as modern web browsers will not recognise it as an image.

    If your code is creating images that give errors then maybe there is something wrong with the code. Maybe you are not writing all of the things into the image that need to be there for the subsequent processing to work properly.
