Display exif information

Display the EXIF information of the photo in Chinese format, and show the vertices in the picture. in addition to some php forums, only three or two information is displayed, which is displayed on lb5000 forums, asp has not been touched for a long time. I don't want to repeat the work. I searched google. except asp, I didn't find any other open-source display exif, so it may be useful to sort it out. There is no technical content. the EXIF information of the photo is displayed in basic Chinese, and the vertices in the image are displayed.

In addition to some php forums, this simple display of three or two pieces of information has been shown on the lb5000 Forum of others, and asp has not been touched for a long time.

I don't want to repeat the work. I searched google. except asp, I didn't find any other open-source display exif, so it may be useful to sort it out.

There is no technical content, basically only the work of Chinese and data sorting. the following code is the main part. all files are in the compressed package and can be widely used in photo albums and forums to display image information, if you want to be familiar with related knowledge, find bugs or optimize them.

At present, a lot of information should be missing, and it should be enough if used only.

------------------
I have seen thumbnails and photoshop images from other people, but I don't know how to add them. Does anyone know?

Thumbnail display :)
