With the ideas that you have given me, I finally found this : http://permadi.com/blog/2010/10/html5-saving-canvas-image-data-using-php-and-ajax/

I will try to adapt the script

As I see, there are 3 way to solve a problem^

Use raw «base64 PNG» image data — for that use common input field type `text`. Than decode it on serverside and save as normal PNG file.
Made JS code for follows: convert `PNG data:image` → canvas → common `img` tag with desired format (PNG/JPG/GIF) → «data:image with certain format». Save it to server as noted in p.1
[not sure for that] Get binary data from base64 and try to send it via AJAX emulating common POST form file uploading (`multipart/form-data`)

Note: you can not use code to attach any data via input type `file` directly.

Thank you so much for the link

With the links, I understand how to save the image created with a button "save-as"

The little thing i'm trying to make is that the data : " data:image/png;base64,iVBORw0KGgoAAAANSUhEUgA............" be added to the input of PageAvatar

Now, I have this => data:image/png;base64,iVBORw0KGgoAAAANSUhEUgA....

but it does not read as a file and it does not work obviously

I tried to change PageAvatar to change the data in the image format and then be read by the plugin but I can not do

In any case, thank you for your help, it's much appreciated

Yes, I understand what you mean but to be honest, i do not like this method with ajax. It creates a tempory files on the website and if the user stop the action, the file does not disappear (with my tests). It would create a cron file to remove the images in the temps folder etc... I find this really paintfull method ^^

I found it easier to ask the user to change the thumbnail if he wanted but only after sending the file and the creation of the first thumb.

Yop,

After some research, I found a script that launches the client-side script.

Here it is : http://marx-tseng.appspot.com/image_crop/index.html

Now I find myself with a new problem, I can upload the big picture with

do you have a solution to upload the second image in an input format (gif,jpg,png) and not base64 ?

Harker .

You need totally rewrite pageavatar: because ints make crop serverside,,. But you need ajax upload + crop and only than save it to server.

It's just another plugin )

What version of «pageavatar» do you use: 2, 3 or 4 ?

Or may be «pageMavatar»?

Hello to all,

I come towards you to find a way of making. At present I use to pageavatar to allow the users to add an image. This extension works well but when I use the crop function it is not still very attractive

ex: http://hpics.li/f0eb7e2

what i'd like is that when the user adds a page it is redirected to the plugin to change the thumbnail generated by pageavatar. But i have no idea on how to do it because after adding a page, it is placed directly awaiting approval. does it go if i add the hooks page.add.last element in my plugin ?

Here is the plugin that i want to add : https://github.com/mkrmpotic/Simple-Image-Crop
