Hello I need create thumbnail of many formats of images. I know how do it on php with help of GD lib. But i need support many more format of files. Please advise me solution of my problem. Thanks. Kind regards, Dmitry
You can do it for as many formats you want. This depends on the GD version you are using. Now more formats are available. To know all the supports available, call your phpinfo() function and see the gd support details.
They will all follow the same technique. You will only need to change the line which creates the new image from an existing. For bmp, I think you will need imagemagick.
