Resize images and save file names in database.

How do you resize uploaded images and save the filenames in your database.

With the Smart Image Processor Extension you can resize your uploaded files and make them the size you want.
This tutorial will show you how to upload the images with Pure ASP.NET Upload, resize the images with Smart Image Processor and insert the filenames of the images into a database.

What will it look like when you are using it?

1. The user will request a page from the server that will enable him/her to upload an image.

2. The user selects the image from his/her computer and submits it.

3. The page is uploaded to the server where the image is resized and put into the folder you specified.

4. The filename is inserted into the database.

Page processing flow: 1. Images are saved in a folder 2. Images are resized 3. Images are saved with their original name, but end with .jpg 4. Filenames are saved in the database.
