Image resizer

[Sunsi]

I understand that this:
https://vborg.vbsupport.ru/showthrea...=Image+Resizer
is a good image resizer, but I understood that you need to have a GD on your server in order to use an image resizer.
So do I need one with this one or not?

GD does not need to be installed on the server. The GD extension for PHP has to be enabled, though.

Go to your AdminCP, then to the Maintenance section. In there you should have a "View PHP Info" section. Click on that and look at the listings. About 1/3rd the way down the page you should see a section for GD. You should look for the value GD Support to see if it is enabled or disabled. Most PHP installs have it enabled.

If you can get the Human Verification Image to appear (the one that looks like this) then the GD extension is enabled.

Thank you!

It is indeed enabled.

But now I've still got the question what image resizer I need. One with GD or one without? I'm confused about what GD actually does.

GD is server side image resizing. This means a lot more work for your server to do when it loads the page, but it also means that more people can view the page.

The alternative is JavaScript image resizing. This is all client side, which means that it's less intensive on your server (this good especially if you're on shared hosting). However, because it relies on javascript it means that not everyone can get the resize (really ridiculously old browsers may not support javascript, likewise with mobile phone browsers).

So ultimately you have to ask yourself, "more intensive on my server? or less intensive but not guaranteed to work 100% of the time?"

Personally, I prefer Javascript. The majority of browsers that access your page will be compatible with javascript. But some people don't like to chance it, that's why they use GD (and if I had a server farm dedicated to 1 website, I'd probably use GD).

Thank you for you explanation!
