PictureSize

[alberto]

First congratulation! this software really works...the only wrong thing being perhaps the name!
I like to make a page with a strip of say 5-6 images at smallest cam size taken every 30 min + the stream video in the center at largest cam size.
This is for my sailing club to show how the weather is now and the last couple of hours. Is it possible to introduce a "picture size setting" also and separated in file-setting?

You are looking for a template that's will display the 5~6 latest images form your cam + Stream or you already have this template and just want a way to scale down images?

Thank you - I have add a table, 6 cells into your _js script. At the moment images are resized by browser. This waist bandwidth stream + images have to be uploaded at page loading . Resize on server would help then.

The code below will:

- Resize images;
- Add date and time;
- Display latest 6 images;
- Delete original images to save disc space;

You need a folder named "files" to upload your images and a folder named "images" to store resized images.

Code: Select all

Thankyou. That was interesting, and I learnt some.

I need a little more than that, however. I shall continue to search and work on it.
