thanks for reply. I did so now, but as i mentioned, I've three attachments fields. how to insert all fields in attachment field. I just copied and pasted three tags in attachments but when I submit two or three files by this, only one file is downladed. What i did, is written below:
1. First i attached two images. And the mail i got, it show two names of images and download links of them, I downloaded both, only second image is getting opened.
2. Then i attached three images and when i downloaded from the mail, only 3rd images is working. though all these images are the copies of the same image.
