Image compression, web optimization in general.

Permalink
Hi there,

My last website is finished and works great. I am working now on making it faster. It is an image intensive website, and when I test it in sites likehttp://www.webpagetest.org/, most of the optimization measures fail. specially Image compression and Cache static content (despite that I have all cache options on).

Anyone knows how to deal with this?

Thank you ,
V.

Optimize image before you upload, I sometimes use:http://photoscape.org

Also add this code to your htaccess file to gzip stuff:
<FilesMatch "\.(js|css|html|htm|php|xml)$">
SetOutputFilter DEFLATE
</FilesMatch>
<IfModule mod_headers.c>
    BrowserMatch MSIE ie
    Header set X-UA-Compatible "IE=Edge,chrome=1" env=ie
  </IfModule>
<IfModule mod_expires.c>
# Enable expirations
ExpiresActive On
ExpiresDefault "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 year"
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
ExpiresByType image/jpg "access plus 1 month"


What is the URL?

Hi @Steevb,

Thank you for your reply... I added the code you said to the htaccess file, and I had also used the "constrain image size" option in most images like I saw you recommended in an other thread.

All images had been saved for 72 or 96 dpi resolution, before uploading to C5.

The link ishttp://www.beautebook.com, I am not sure the htaccess new code is working, hover images are very slow and the page in general takes a while to load. If you could take a look that would be great,

Thank you again...

Okay, I took the liberty of optimising a few images and managed to make 75% saving in weight, see attached.

If images work for you, swap out and see if webpagetest and pingdom give better results.

Thank you @Steevb,

I replaced all images with the ones you gave me, thank you so much.
I have a question, your images are the same size and resolution (72 dpi) than mine, how come your files are much smaller? Is there another variable other than size and resolution?

Thanks a lot for your time and your help, your advice has been very useful.

I used Adobe Fireworks, but you can use the image editor I recommended in previous post. Does the same thing, but not quite as good.

photoscape.org

The program does the hard work.

To elaborate:
I open my images/photos in the editor and crop/trim/adjust colours or whatever and ALWAYS try to save/export as a jpg.

From my experience using some other photo editors .i.e photoshop, things will never work out.

Sorry, didn't actually answer your question.

They came into the program from you site. I left everything as default. The output became a quality of 80 at 72dpi.

Yes, my images were done on Photoshop, save for web, as you said, it doesn't work.
I found this one online, it is extremely simple and works very fast and well, I leave the link for the record:

http://compressjpeg.com/

Thanks again!

Okay, but I can still get an image to weigh at least 15% less!

Also forgot to mention, I don't trust online stuff and photoscape is FREE.
