Hi
Is it possible config images size for users.
Example
max size 500x300 px and 30kb.
Thx for help

For uploads I think that is left to the site administrator to handle rather than being a configuration option within FCKeditor... Upload limits can be set either in your .htaccess file or via PHP's ini_set()... I have never seen pixel size limits as being an option as the file would need to be uploaded before any such determination could possibly be made anyway...

[TedD]

In CKFinder (CKFinder is a powerful and easy to use Ajax file manager for web browsers) it's possible to resize images. CKFinder is very easy to integrate with FCKeditor and Etomite 1.1

I know I have something to do that.
It's a image uploader, I've made sometime ago, it isn't finished, but functional, I think..

What it does(this is from my memory, so I could be totally wrong here.. )
it checks the image upload for size, and if size is OK it save it to a temporary folder.
Then it adjusts it to the maximum size if the image dimensions are bigger,
and transfers the converted image to the destination folder.
It then deletes the original uploaded file.

That's it, I think.
So the uploaded image is converted to the preset dimensions, or smaller.

I have the source somewhere, It worked under PHP 4.
I don't know if it does with PHP 5.

If you like to see the source, I'll have a look in the big dusty archive or lost code's

I also have a piece of code that I use for resizing images all the time... Not sure what the exact need here is, but if the code is needed I can try to post a generic version here... I also use another version of it to save a thumb and a resized image...

[Ed Headset]

I'll see if I can post it here, so you can see how I've done it.

I'll have to translates the commets, as they are in Dutch..

For me it isn't necessary to translate from Dutch to English because I'm a Dutch CHEESEHEAD (from Alkmaar)

Forum language is English so..... it's your decision...

I'm curious what your solutions are. Is the quality (for example 90% *.jpg) also adjustable ?
With CKFinder you can change the quality in %s of images and thumbnails when you upload an image.
Licence for a single website $ 59,- and Licenses CKFinder to be used inside pages of all web sites owned or produced by me $ 590,- To expensive for me

Kind regards
Ted

I know you are a fellow countryman but this forum has English as it's main language.
So I'll add some translation to it, so everyone can read the comments

Hmm I'm not sure what you mean, but I think so.
As this is a very old one <* blowing the dust of*>
It worked, but maybe it's not usable, but might give you an idea

Thinking back I realise it's maybe not very well set up/programmed.
As I recall this might be of my first projects in PHP 4.0


Here's the code:

Hi Ed,

I tried your script and it didn't work. For the time being I'm using CKFinder.
A lot of us, open source CMS users, are searching for the perfect on-line image editor and editor.

Thanks a lot
Ted

[Ralph]

The Advanced Image Manager in the newest release of Xinha works quite well and can probably be integrated into other editors... It allows resizing, cropping, saving in alternate formats, etc... The version in older releases isn't bad either but the newest one has more features...

No Problem Ted,

But I was afraid it didn't work anymore.

I'll have a go at it, see if I can get something out of it

[edit]
Just checked it out, locally on my Wampserver, and it does work!

To get it working you need to do the following:

On line 1 change "<?" in to "<?php"
Yes I used to use short tags

secondly create a folder where the source is, and call this one "bestanden" open rhis folder
and create a "thumbs" folder, and it should work.

The upload is stored in "bestanden" and the thumbnail is stored in "thumbs"

Images are renamed to image##.jpg and so are the Thumbnails.

This even works with PHP 5.2.6.


BTW: I've updated the code, I've found some errors in the translation, and I've added php to the <? tag
