I have the below info from the PHP manual:
Can someone please explain to me or show me a good tutorial on how to create thumbnails of images after uploading them? I already have the upload feature working, but I need to create thumbnails. Any help greatly appreciated.
ImageCopyResized -- Copy and resize part of an image
Description:
int imagecopyresized (int dst_im, int src_im, int dstX, int dstY, int srcX, int srcY, int dstW, int dstH, int srcW, int srcH)
ImageCopyResized() copies a rectangular portion of one image to another image. Dst_im is the destination image, src_im is the source image identifier. If the source and destination coordinates and width and heights differ, appropriate stretching or shrinking of the image fragment will be performed. The coordinates refer to the upper left corner. This function can be used to copy regions within the same image (if dst_im is the same as src_im) but if the regions overlap the results will be unpredictable.
