Added image resize options to download

[maxxer]

Requires himiklab/yii2-easy-thumbnail-image-helper

Something is wrong here. I cannot test that cause I have a memory limit when I try to print AttachmentsTable:

PHP Fatal Error – yii\base\ErrorException
Allowed memory size of 134217728 bytes exhausted (tried to allocate 14728 bytes)

That should not be cause 128 MB is enough

[maxxer]

How many images did you have attached to the model? How big are they?
Maybe there's a memory leak in the EasyThumbnailImage::thumbnailImg call?
I tried with few images and worked fine...

I tried now with 6 images bigger than 2M each and I didn't have any problem in displaying the widget

It's very strange behaviour of the script on my Mac. I still dont understand the problem. I have attached only one image with size of 150 KB

[maxxer]

maybe php version? I tried on 5.5 and 5.6

This is a great option when it comes true, why do not resize when you first insert to the database?

Sorry I was too stupid and could not pull request, but this time I saw a great resize behavior
mongosoft : UploadImageBehavior
zxbodya : ImageAttachmentBehavior

Whether it could be implemented here ?
