S.L.P. Raspbian old image optimization

Post by zoldaten »

I noticed that when page loads tons of time taken by loading images ) :
2021-03-17_20h42_39.jpg
2021-03-17_20h42_39.jpg (8.12 KiB) Viewed 177 times
So to speed up i just pass them through optimisator and result became:
2021-03-17_21h09_25.jpg
2021-03-17_21h09_25.jpg (6.68 KiB) Viewed 177 times
So to do so u just need to upload optimized images and replace old ones. It can be tricky as there`s no VNC.
I recommend ftp. For example - https://www.xlightftpd.com/
After that u can upload them this way:
2021-03-17_21h18_47.jpg
2021-03-17_21h18_47.jpg (15.43 KiB) Viewed 177 times
New images -
new_images.zip
(145.39 KiB) Downloaded 14 times
Next i`ll look after js may be it can be optimized too.

What have done ?
All external links of js and css put to filesystem (most of all).

To do that you need put updated index.php to /var/www/html/files
And js and css after unpack to /var/www/html/files/js

Files -
js.rar
(239.72 KiB) Downloaded 13 times
and
index.php.rar
(28.3 KiB) Downloaded 14 times

On push it just shutdown stereopi :mrgreen:

To do the same put to /var/www/html updated index.php -
index.rar
(4.09 KiB) Downloaded 14 times
and to /var/www/html/imgs -
shutdown_icon.rar
(26.68 KiB) Downloaded 13 times
(after unpack ofcause).

Make shutdown.php at the same dir where index.php is and put in it 1 string:

Code: Select all

<?php system('sudo /sbin/shutdown -h now'); ?>
Make shutdown.php executable:

Code: Select all

chmod +x shutdown.php
