WebPerf Optimize Images

Is this wordpress site ? You should combine it with EWWW Image Optimizer + Imsanity i.e. Wordpress - Playing with EWWW Image Optimizer Wordpress Plugin. This allows automatic upload resize/optimisation in lossless format first in free EWWW plugin. Lossless optimisation usually only saves 2-5% overall for already ok optimized images and up to 5-20% for others.

Then set optimise-images.sh via cronjob to work on /upload directory full path i.e. /home/nginx/domains/domain.com/public/wp-content/upload to do lossy optimisation on resulting EWWW images. The lossy optimisation boosts the image size reductions to between 20-85%.

Currently, no way in optimise-images.sh script but if you look carefully in the optimise command verbose output you will see if you re-ran optimise mode on already optimised images, you don't do much at all

example of re-running optimise-images.sh optimise mode on already optimised directory

But I can see the problem you're describing. I could probably could add another mode to only look for images created/new in last XX hours i.e. 24hrs to process to limit the duplication of processing.

 

the optimise-images.sh lossy optimisation is for JPG/PNG only while keeping WebP IMAGICK_WEBPLOSSLESS='n' disabled

 

Updated optimise-images.sh with new profile-age & optimise-age Mode which allow you to filter and limit profiling and optimisation of images by image timestamp age

 

slight correction, optimise-image.sh only operates 1 level deep so need to do some scripting as outlined at GitHub - centminmod/optimise-images: Batch image resizer, optimiser and profiler using ImageMagick convert, OptiPNG, JpegOptim and optional ZopfliPNG, Guetzli and MozJPEG. so to process directories at /home/nginx/domains/domain.com/public/wp-content/upload/2017/XX where XX is month

i.e. new optimise-cron-age mode to filter by image timestamp age + specifically made for use as a cronjob as it saves processing time by removing the post-optimisation profile run. Set UNATTENDED_OPTIMISE='y' to disable the backup directory prompt so you can run unattended first. Edit optimise-cron-age command for command you want to use.

Code (Text):

find /home/nginx/domains/domain.com/public/wp-content/upload/2017/ -type d | sort | while read d; do echo "optimise directory: $d"; echo "/root/tools/optimise-images.sh optimise-cron-age $d"; /root/tools/optimise-images.sh optimise-cron-age $d; done
chown -R nginx:nginx /home/nginx/domains/domain.com/public/wp-content/upload/2017/

add a chown command to change file user/group permissions too

 

whoops yeah now you explain, yes that is what FIND_IMGAGE does optimises stuff older than heh

will fix it

 

fixed bug - changing one character from + to - made the difference fixed bug in profile-age, optimise-age · centminmod/optimise-images@cd1071a · GitHub

 

working on a new option add ADD_COMMENT='n' option · centminmod/optimise-images@ab1c7d3 · GitHub

haven't done the skipping routine yet just putting the marker comment option in place first

 

@Fernando @Matt will like this

• 18/08/17 New Option: ADD_COMMENT variable marker to skip previously optimised images

thanks for testing, bug reporting and feedback

 

not sure i understand whitespace in code or output table ?

got a diff of before and after clean up of optimise-image.sh ?

edit: of you mean like

Code (Text):

 grep -n -P "(\%-\s+[0-9]|[0-9]\.\s+0f|\%\s+-?[0-9].*?0f)" optimise-images.sh                    
1024:        cat "$LOG_PROFILE" | egrep "${COMPARE_SUFFIX}.jpg :|${COMPARE_SUFFIX}.png :|${COMPARE_SUFFIX}.jpeg :" | awk -F " : " '{c3 += $3; c4 += $4; c5 += $5; c8 += $8; tb = c8; tk = c8} END {printf "| %-9.0f | %-10.0f | %-11.  0f | %-10.0f | %-18.0f | %-15.0f |\n", c3/NR, c4/NR, c5/NR, c8/NR, tb, tk/1024}'

the space between

Code (Text):

%-11.  0f

i will check thanks

 

Cheers fixed them all fix & remove extra whitespaces in output · centminmod/optimise-images@e49e72b · GitHub I blame it on SublimeText editor's macros + line auto wrap
